Most of that are valid business decisions. Just because you disagree doesn't mean that FB is shady. You're free not to use their service. Political censorship is often mentioned in these discussions, and it's exactly what I meant with controversial. I don't think there's a way to satisfy everyone. Telegram doesn't censor and they're known to be the favourite tool for many terrorists to communicate, which is something that would probably upset more FB users than censoring critical posts.

The tax policy could be different, but Facebook is no other than most American companies. Other services will only have different policies if they are either not based in the U.S. or don't make enough money abroad to justify these constructs. It's the job of the Government to introduce more sensible tax laws, not using Facebook won't change anything.

What's the issue with using your "real name"? Honestly I think that should be the policy more places, so people aren't hiding behind their online personas.
