How is Facebook monopolising social discourse? Have you not heard of Reddit, Twitter or Instagram?
> A lot of the industries you mention don't try their hardest to get my attention
Huh? You don't think those industries run any advertising campaigns?
> there's no way I can communicate with Facebook users unless I am also on Facebook and accept the ToS and "privacy" policy.
This is the strangest complaint I've ever read. Are you suggesting anonymous people are able to message Facebook users without agreeing to any terms of service? I definitely can't see anything going wrong with that. Why not ask them to message you on one of the 1000 other messaging apps? No one's forcing you to sign up to Facebook, it just sounds like it's being successful at providing an easy way to message between friends.
