Part of Trump's argument has been "the system is rigged" so this support it, especially once you consider that Twitter did not ban people calling for protests during the Arab Spring. In fact, the State Department - run by Hillary Clinton at the time - specifically asked for Twitter to keep accounts open and information flowing.

This is ideal for Trump and crew.

In the US, the Net Neutrality position describes internet access as a utility, not a luxury. Further the UN declares it a Human Right. If either/both of those positions hold, then the gatekeepers - Google, Facebook, Twitter, etc - suppressing any view or blocking access to any group could be a violation of human rights.

I think that will have to be settled in court, but it will get messy for those companies.
