Technically, it can be more complex than that. For example, if Facebook was tax-payer funded, then they should be liable in the same way government is supposed to be accountable to the voters who also pay taxes. In other words, if Facebook is governmental, then they should not be treated like private companies. Also, Facebook should have been honest from day one concerning their rules. But one of the problems is in how Facebook changes their rules again and again and Facebook selectively enforces their rules when they want and to whoever they want. Facebook said it was a platform for all ideas and Facebook has violated that statement. That is a scam. So, they should be sued or taken to court for fraud and for other things as well including violating the fourth amendment.
