Okay here what noone talks about android is linux at its core if android and linux were merged it wouldnt to hard of a parject but the issue is time and resources. If linux and android were merged as open source it screw up the entire system and google would be screwed and thwy realised that and thats why their quietly trying to do it first.

Lowkey postmarketos isnt where its at sorry i think mobian would be better because look at debian, ubuntu made it better but not quite there and then we got mint and zorin. I think the same will happen mobian and postmarket is based on mobian. Also kde and gnome are the one that need the funding since they run the gui/desktop environment.

Some fdroid apps are absolutly goated that you cant get on playstore

They are, graphene will be getting a side launch with a major distributor about a year a after launch and you can mamual install it when the flagship is released. The reason google phones buy is so people can install graphen lol.
