These companies are already in the dark deep of hyper partisan censorship. Take reddit for example. Nearly every sub is a left wing echo chamber, with essentially the same comment being made, and opposing viewpoints hidden, shadow-banned, or deleted under the guise of 'disinformation' even if they are factually accurate. Some of it is partly driven by liaisons within US and other governments, and supported by media. That is both problematic and terrorizing. Media was always supposed to be a counter-balance to government over-reach, but today, media is in on the scheme.
Except you can start your own subreddit and choose your own moderation policies. The inaccurately named /r/conservative has a lot of traffic and there are many more.
Being able to start a subreddit is meaningless, when right-leaning subreddits are systematically shut down, or restricted to the point of becoming inoperative, as soon as they pass a certain threshold popularity.
That's a funny joke considering 99% of subs which don't carry water is eventually banned for "misinformation" and is filled with bad actors and sock puppets.
That depends where one finds oneself on the political scale. A communist is only going to find neoliberal semi fascist conservative consensus where someone on the extreme right finds a socialist echo chamber.
What reasonable viewpoints do you perceive are being deleted and accused of being disinformation?
Stuff like /r/shitredditsays exist/existed to point out reddit being misogynistic, and capitalism is the name of the game for all the large subreddits.
I don't think you'll find a large subreddit that is actually leftist. It's just centered on what the population thinks, both for overall trends and for the reddit user base.
This doesn't match US politics because US politics don't match popular opinion, driven instead by the arbitrary layout of states and congressional districts
