Nobody is going to go to OP's personal site to watch videos. They are going to fire up YT and eat what the algorithm feeds them.
The reason PeerTube and Nebula are important is it provides the potential for a true alternative destination for people looking for videos. Once these platforms have an enough content to draw an audience naturally, then content creators will be able to survive a post-YT world.
For people like the OP, it's probably best to follow the model video games do with DRM. Post on YT first, to get the ad revenue, then repost on other platforms after some time to build up an alternative subscriber base. Presumably, in-video sponsorships will pay for these views as well, even if there's no direct ad-sense like revenue model.
People have been following this strategy of creating their own mini-brands for years and have their own following. YT doesn't even have all of the their content, and YT is just one lead gen channel. Frankly, Ad Revenue from YT is pitiful, and it's an open secret the real money is made as I've described (although it is a long term play).
I don't disagree with you about PeerTube and the like, but it is a two-sided marketplace and you need to prime both sides of that pump (content creators and viewers).
You need to build a product so good that my statement above sounds INSANE. Not just “I think he’s wrong” but “dude absolutely no way. Everyone will want this. Are you stupid?”
And this is not that product.
Edit: yeah. I was curious so I went searching for ASMR videos. The default search brought some (terrible-looking) ones up, but half of them were in French? I sorted by views instead, and even though I literally only searched for “ASMR”, there were no longer any ASMR videos near the top of the results. For something trying to compete with YouTube, this is a very mid experience. Nobody is going to waste time migrating.
Edit: Of course, you do need to have enough demand/scale to make it worth your while, but that will depend on your audience size and how engaged/invested they are in your content AND you personally to an extent. Perhaps be creative and start out with small experiments. Not too hard with LLMs nowadays.
That one is likely the best use case while one monetizes on YT waiting for FreeTube to gain more popularity. Worth also for keeping a safer online accessible backup in case things go south with the YT channel being taken down for any reason, be it bogus copyright claims or else. What I'm not sure of though is how long until Google changes YT rules to disallow linking or even mentioning competing, or perceived as such, services. Companies always do that: I'm a Ebay user since 2008, 100% feedback both as seller and customer, hundreds of positives not a single negative or neutral in 18 years, but a while ago Ebay in their infinite wisdom blocked a listing of mine because I added the links of the documentation needed to use the device I was selling; no way to appeal successfully or have it restored, they evidently either used a monkey or AI to detect what they identified as an attempt to contact the customer outside of Ebay, for a €30 item nonetheless. Years ago they didn't enforce such idiotic limitations, so I wouldn't put any trust on YT to remain consistent with their current rules.
