Anyone even remotely privacy or security conscious needs to vote with their wallet in protest and stop buying Android phones, otherwise it's only a matter of time 'til Google bans side-loading and it becomes impossible to buy a phone that can run any kind of anonymous or end-to-end encrypted communication software.

GrapheneOS is a beautiful stop-gap, but there are real bona-fide Linux smartphones out there. To be clear, there are not many, the hardware often isn't great, the software often isn't great. PinePhone and Librem come to mind.
