I as far as I know the best OpenWRT AP’s / Routers you can buy right now is the Banana Pi R64, R3, R4(Still in development). Open source firmware with a long support life of updates and security patches and a nice metal casing.
I say as far as I know because I have not bought one yet as I don’t have the funds for that right now. It is my next AP replacement though.
I think the only way it makes sense for Framework to get into the phone market is to follow the footsteps of Pine64 trying to create Linux phones. There’s no point making a phone at an inherently higher cost to make it more durable and repairable with a “closed SDK” SoC that has a fixed EoL date. I made a more detailed comment about this in the main thread.
