@twann I am using MicroG and it is definitely not for everyone. I can't tell if Google Drive works but I would guess that it will work. The bigger problem are banking apps and similar ones because Safety Net is not working with MicroG. This means some banking apps recognize the device as "rooted" and won't start. If someone uses MicroG they should definitely have the mindset that some not working apps are better then getting spied on and the patience to fix some problems.
@twann I am using /e/ OS (e.foundation) because it has MicroG perfectly integrated into the OS and doesn't need any additional work. Furthermore, they removed everything that sends anything to google. They even changed the timeserver.
