Edit: Apparently Motorola is doing just that.
Otherwise Huawei would have already jumped into that gap. They have their own Google-independent OS now so they could have marketed it to privacy enthusiasts where the lack of Google services would have been a positive not a negative.
Xiaomi? Privacy?
Apple didn't "cash in", their marketing dept made sure privacy/security engineering got just enough budget to pull off miracles & then spend even more to successfully make the public forget about the very nasty Celebgate.
That was a phishing campaign, not a breach.
Source you can't compile or install onto the device wouldn't be very useful.
The Linux kernel developers see what Tivo did as a "feature" rather than a "flaw" and refuse GPLv3.
Linux is no longer the community-driven choice. It's big business with billions hanging on the line. The grassroots origins are long over.
While I agree with your general sentiment, I feel necessary to acknowledge that it's just not there (yet?). GrapheneOS is a great option if you want to have a fully working and secure device.
In the end I just opted out of the android ecosystem altogether and went with a flip phone that I used as a hotspot for an iPod touch (we only used over VPN with locked down DNS and nothing google related).
My privacy lasted about two weeks, because unfortunately Spotify was able to fingerprint that device to Facebook.
At the time? They still are the only devices officially supported.
Having your freedom be tied to a handful of devices from Google, is a massive supply chain risk.
Your provider can run arbitrary code there.
