Nobody thinks there is a big problem with online censoring that needs to be dealt with?
Certainly no platform is anywhere close to banning the ideas or platform of the Trump campaign or the Republican Party - they get debate and discussion but they certainly are not censored. They are firmly within the mainstream.
(I also think, in a broader sense, that people need to not rely on big for-profit tech companies for unpopular ideas. I think it's good for society that everyone from the boogaloo folks to the Unabomber get to be able to publish their ideas, even - and perhaps especially - when those ideas involve violent revolution to the social order. But I also think it's foolish to expect platforms that are profiting handsomely from the stability of the social order to fairly convey those discussions, especially if any of those ideologies gets close to making a difference. So, even if I thought that we had a problem with the big tech companies censoring discussions, it doesn't seem like a problem worth solving.)
