This is a facetious reply, but I don't think the government's punishment of free speech violations would have to be totalitarian to be highly concerning.
Likewise, I think allowing a handful of tech employees and billionaires to control what is and is not free speech -- without any democratic control or regulation -- is also highly concerning.
It blows my mind that the so-called left is advocating for the right of private, global, monopolistic corporations to act with impunity.
