For me it’s Whatsapp. Like 99% of people i know use it so yeh… i still need it. I am considering moving the Whatsapp Gdrive backup to a local backup btw.
Google photos is also a major problem for us. We have a lot of stuff that want to migrate to different service (or store locally).


im fortunate here in australia my friends and family use telegram with me, i use signal but it’s so utterly basic no one else liked it, also there was a bug where the desktop app would spam people you’re talking to a million times a second causing your friends phone to damn near explode, that was embarrassing :/
there are some it guys who do use signal but we’re a tiny minority but as telegram is my main messenger i don’t use meta at all
google on the other hand, there is no alternative to google maps (reviews and easily findable opening hours) or youtube
i currently have an iphone xs but my next phone will be https://murena.com/
so that’ll remove apple
then that’s about it, until a european CPU and GPU that isn’t amd/intel/nvidia comes along or until dailymotion suddenly leaps forwards in video content or ecosia creates their own maps ive gone as far as i can
