Drawback: You need different silkscreens for different amounts of RAM.
Btw, if you're worried about RAM-swapped units you can already verify them as described at https://geekworm.com/blogs/news/prevent-ram-swapped-raspberr...

These operations are not hobbyist level, they have access to the machinery to make it trivial.
It is so trivial anyone that's ever done fingernail polish can do it. The process is roughly the same.
They also added a bit of internal ink, which is worth just a little more:
> we now also program in some other device attributes, meaning that switching parts of the same size may not work.
Working with vendors in China is entirely adversarial (mostly because their supply chain is vulnerable too), at this scale.
the only reason why pis are not marked this way is because raspberry didn't wanted to (so far)
Replacing a socketed component that is modular by design, even if it's not officially intended to be upgraded outside the factory, is worlds different from replacing BGA components on a densely packed PCB.
That said, there could also be a middle ground by just providing some way to look up the hardware specs of a given serial number. Post the part numbers of the components that you're concerned about being replaced and provide tools to verify as many of them through software as is practical. Allow owners to know if their device has been modified and how so, but allow them to choose what to do with that information.
Combating fraudsters trying to pass off modified and/or refurbished devices as genuine is valid, but preventing owners from modifying or repairing their own or knowingly purchasing such devices from honest resellers is not.
I'm sorry, you seem to be confused. Soldering is not the problem. Locking up the hardware to have hardware provisioned tier limits to block you from upgrading your own hardware is silly.
And do note, raspberry pi doesn't prevent you from switching RAM chips. The board will continue to work just the same with high capacity variants. But for some reason raspberry pi hardcodes a max memory size that prevents you from using the hardware upgrade you paid for in full.
They don't need the resellers help for that! I've already been burned twice thinking "I'll use a raspberry pi for this small project" and having it die within a month because reliably reading/writing to an SD card is hard or something.
Between the notorious unreliability, crazy price hikes, trademark or whatever disputes, and this anti consumer ewaste generating policy, I can't think of any reason I'd ever patronize them again.. my only regret is it took me two purchases to learn this lesson!
> When the unit doesn’t work correctly, the anger and RMA requests are directed back at the Raspberry Pi
It's not their problem then, the seller is responsible for it and I think we can assume the user has a brain so they knew they could buy a more expensive option from the authorized sellers. Isn't this the case?
Dangerous assumption there. I'm not just being cynical, that is decades of experience speaking.
in those jurisdictions where either price discrimination or locking hardware are not illegal, it is typically perfectly legal to reverse engineer for compatibility purposes. So nothing prevents such resellers from upping their game and learning a thing or two about link training and general SDRAM bringup.
Once they have acquired the knowledge legally in such jurisdictions the product just flows in the other jurisdictions anyway.
Courts upheld the monopolistic position of microsoft etc. for decades, but respect has no finality, "re" + "spect" to review, so later such companies were fined for their decades long transgressions.
But during those decades it may appear legal to the average consumer.
Inaction is not permission.
Reverse engineering is legal, but manufacturers don’t have to help you figure out how to reverse engineer their products and they’re allowed to design their products in a way that makes it difficult.
There’s generally not a lot of jurisdictions out there that make stuff like hardware lockdowns of this nature illegal, especially for companies that are not in regulated industries or are not monopoly/oligopoly players.
> Reverse engineering is legal, but manufacturers don’t have to help you figure out how to reverse engineer their products and they’re allowed to design their products in a way that makes it difficult.
I'm not asking for help to figure this out, and of course RP is allowed to shoot themselves in any foot they like.
Consider Europe where such reverse engineering is perfectly legal for compatibility purposes. Let's consider an idealized scenario, there were no security bugs or other issues with the product that would justify reverse engineering RP blobs in public. When they do something like this, they are GIVING CARTE BLANCHE to public reverse engineering efforts to attain compatibility with other RAM chips. Why would you provide legal cover in some jurisdictions for others in publicly reverse engineering your own products by introducing artificial incompatibility?
Also from a consumer perspective, RP tries to place itself front and center in maker communties, emphasizing modularity, not just hobbyists, also companies build and design end products using RP units. All of these companies must now be wondering where RP Foundations exact red line resides: can we resell an RP board in a Kiosk we made? or only for as long as it doesn't compete with RP's future Kiosk modules? Today its the RAM upgrade, but tomorrow RP modules may refuse to boot some popular Kiosk hardware intentionally. What prevents RP Foundation from eventually "not copying" end-application hardware like a Kiosk design from their customers, and then enforcing compatibility only with RP Kiosks?
So not only are they providing legal cover for public reverse engineering efforts, they are scaring part of their customer base.

That's a very shallow interpretation of law, looking only at what RP is or isn't allowed to do.
There's generally not a lot of jurisdictions out there that make stuff like reverse engineering for compatibility or security applications illegal either.
I doubt antitrust would get anywhere on this RAM issue, but antitrust law is not defined in terms of either of those categories.
Doing a RAM swap and then selling the resulting unit as if it were a Raspberry Pi of the higher RAM capacity might be construed as trademark infringement[0]. And in general it's fairly difficult to make arguments in antitrust cases that boil down to "yes, your honor, everything they're doing is within their rights but I don't like it".
[0] At the same time, the scammers could probably get away with this by putting "Upgraded to 16GB!" in the title of their eBay listings or whatever, in the same way that fraudulent storage devices are labeled as "upgraded" (read: lying about their capacity). That doesn't impact the antitrust analysis though.
But if this is the real concern, they could just display the fact that "Unoriginal RAM detected" to inform the user its not a vanilla RPi Foundation product, so buyers understand the situation, but continue booting normally.
Every board sold would have been an extra user, the reseller isn't adding full users (although they may increase the indirect customer base!), so even gaining a user through a reseller increases the amortization divider for the support burden.
Now lets consider RAM chip support burden, the original Pi RAM chips can have issues generating support burden, and so can the reseller RAM chips. Unless RP foundation refuses to upstream link training / RAM bringup patches from resellers, there is no real additional support burden.
In fact if RP were a little more creative, they could have tried contacting the resellers to explain they can continue their modding business as long as they advertise it clearly as modified, and to inform them they will be receiving units that didn't pass the RAM tests from the automated lines, since they're going to desolder the chips anyway, this can save costs for RP foundation.

If someone gets updated in the wild (like this person did without realizing they had a counterfeit board), they'll fail to boot.
In short, someone at NVIDIA really hates retail, but loves Chinese sanction busters.
