You got it correct with "legal repercussions". Getting banned for TOS violations is hardly a legal repercussion, it's just someone exercising property rights. Nobody should have to pay for someone else's speech, good, bad or indifferent.

Lack of legal repercussions is also not lack of social repercussions.

Maybe we should be insisting on American companies retaining core American values, but that's not the legal environment they operate in, which is one of "fiduciary duty" only.
