Sadly for phones for example there is currently not that much choice, you can pick android with googles spyware or pick iOS, the linuxonphone things might improve this hopefully. we will see.
I’m kind of bumped there is no european alternative for many of these things, Haiku is kind of that for a Desktop OS though.
The eu funded minix3 for example but i don’t see it usable as a desktop or phone OS anywhere : /
