Assume for a moment that it does. The company is entitled to enforce its terms of service; the only potential caveat is that it may be considered a public accommodation, in which case it can’t discriminate against users on the basis of race, religion or other protected category.

It would be just as entitled to ban all criticism of Trump or Zuckerberg or any other person its management favored.
