When this whole thing got announced, I purchased a new Pixel 9 and flashed it with GrapheneOS.
I am hoping that in about 6-8 years (when I realistically need to update) the landscape might be a bit better. Or who knows, maybe I'll just continue using GrapheneOS.
So far I have not had a single issues with it. Apps the rely on attestation do not work, but honestly it's only two applications out of hundreds so I can live with it.
I also financially support GrapheneOS on a monthly basis (15$). This is just too important of an project not to.
The new phone is a nice reward for Google for this announcement
I think the EU should pile in as well. It's basically an oven-ready independent mobile OS.
