There have been cases where relatively high profile people have had trouble for valid reasons, which they have denied - however, I agree that these sites clearly remove many people for their own personal / private convenience and not due to any rules having actually been broken. It is truly in the interests of the political controllers to have people corralled into controlled networks and this can never be a good thing for 'democracy' (whatever that really is!). If the norm for communication and promotion is the internet and nearly everyone uses one of a small number of censored platforms, then real communication cannot happen and therefore the interests of humanity are flushed down the toilet to a large extent.
