Maybe I'm misunderstanding you but the bill of rights is specific to actions taken by the government. Of course individuals and corporations are free to censure individuals on their platforms as long as they are not doing so at the direction of the government. A kid can't waive the constitution in their parent's face when they barge into their room without knocking, even though they have a right to privacy and protection against unreasonable search and seizure.
