In theory maybe, but in practice we're nowhere even remotely near that. E.g. Twitter is full of very vocal politicians complaining loudly that their political beliefs are being, er, silenced on Twitter. It's all part of the show.

The western media landscape is incredibly diverse, pretty much every conceivable opinion and niche community is available and discoverable. In fact there seems to have been a huge boom in fringe attitudes and beliefs, as barriers to communication have fallen away, exactly the opposite of what you'd expect if communications was being meaningfully restricted and moderated at the societal level.

There's a difference between availability and prominence. What we have right now is a media market (both on and off the Internet) that's dominated by a few large players that represent very few political ideologies. And then, yes, you have "every conceivable opinion" on the Net - but, more often than not, you have to already know that opinion to find more about it, because it ends up shoved off the main platforms into dark corners.
