If Biden's handlers are doing this it's more than likely because they are paranoid and looking at what big tech did to Trump and other conservatives and wondering if their partners in crime might do that to them if they get out of line. Big Tech has the power of social media along with ownership of most major papers/magazines and news media at this point in time. Old saying was never bite the hand that feeds you and in this case it's certainly possible that the question is who controls who.
