Facebook built a monster that eats democracy and shits cash. Now Facebook has lost control of the monster they set loose on the world.

Governments are trying to control it. Sri Lanka recently disabled all Facebook properties at the ISP level after Facebook promised to clean up incitements to violence but then either wouldn't or couldn't.

Just because a thing is legal doesn't make it moral or ethical. And a big reason why bad things remain legal is because bad things tend to shit cash.

I suppose you're free to do anything that doesn't get you arrested. The rest of us try to live to a somewhat higher standard.
