Motorola + GrapheneOS next year could be an alternative. So far they've been relatively insulated from the changes that have been coming down from Google.
I'll be waiting.
In the meantime, I'm currently using a low end Motorola moto g 5G 2023 which lets me turn off Play Services. Chrome and the Google Calendar don't run (really do need to find a replacement calendar), and I couldn't be happier. Motorola's interest in GrapheneOS makes me wonder if they did this on purpose.
Or if you need it now, Pixel + GrapheneOS. Pixel A-series are really affordable. E.g. the 9A is 350 Euro here, have great device security (Google Titan M2 hardware security processor, CPU that supports MTE, etc.), pretty good cameras/camera processing, etc.
Motorola won't change a thing about hardware attestation. GrapheneOS is locked out from reCAPTCHA because GrapheneOS is signed by GrapheneOS and not by Google.
The way it's going, by the time the Motorola + GrapheneOS phone is out, it will be a lot more painful to use GrapheneOS than today. Not because of GrapheneOS of course, but because everybody accepts that bullshit Google is doing.
If you're waiting for Motorola + GrapheneOS, you could start complaining to banks and other apps that don't support GrapheneOS :-). If enough people did that, maybe those companies would consider it.
