Yes they can but it ended up costing them billions in lost shares....like he said "at what cost" and it was expensive. I find it odd you think this is okay, there was nothing the president said that day to insight violence, he was banned because he told them to stay peaceful, that we were the party of law and order and respecting law and order...the part that got him banned were these horrible words "we know the election was stolen from us". If Americans allow this to stand we'll see what we also are seeing, platforms losing market share threatening to shut down access to what should be an individuals right to go to another platform. When and where does it end? I've said before that one day people will look back at those at the capitol with respect because once they're rights are eroded, and it will come, the distain for the man holding office will be no where near the distain they will feel having their rights taken away.
