@as400 @Em0nM4stodon State is more restricted than companies, and for good reasons. And no, when using POTS, companies can't just spy on you. Same protections don't apply to Facebook (etc), I'm afraid.
I agree that privacy is neccessary, but I'm afraid selecting country and learning how its laws work will be needed for that...
EU may have more privacy protections than your country, in such case it may be good to study its laws :-).
