hahahahaha 2k for a phone that cannot last a day. yeah no. i d rather go for a redmi with postmarket os. it does not even have a blob free modem
If you go with postmarketOS (good!), and don't want to touch anything that touched Purism, better avoid anything GTK (Phosh, GNOME Mobile and related apps). While Purism did not make a competitive phone, their investments into libre software went great and keep paying off.
