Facebook, on the front end, manipulates what you see just to piss you off and increase "user engagement". On the back end it collects and sells data to anyone with money (see Cambridge Analytica, and whoever else). It is a filthy game, but a different game. They don't filter/block what you say/write, unless you go very extreme with your opinions posts. To ensure that I am not defending Facebook, it is a filthy company, with filthy management, and filthy agendas. Unfortunately they provide the 1-2-5-10 useful features that have captured some audience that would have otherwise dropped them.
