I have been reading for years now that conservative viewpoints are suppressed on places like YouTube, Facebook & Twitter.
So why haven't those people banded together to create some alternatives? Would seem there is an opportunity to strike it rich by creating a competitive platform if it is really that big of a problem.
There actually are and have been alternative social media and streaming sites started up, even ones that have been around for years, they just don't go very far when competing against the established giants. In my opinion, Google is part of the problem. Considering that they own the vast majority of search traffic and they also own YouTube, popularizing an alternative user-created-video-content-streaming site would be, to say the least, tricky.
Another part of the problem is the publicity some of the alternatives get. In the age of Trump, anything that is identified as specifically conservative and anything specifically championing free speech is generally characterized, by the mainstream, as racist, sexist, homophobic, Islamophobic, transphobic, xenophobic, fascist, and sympathetic to Nazi's. A young website trying to compete against near-monopolies gets stuck with these sorts of labels before they're large enough to reach significant numbers of people with rebuttals against such accusations is all but doomed right out of the gate. Then, once it's "established" in the court of low-information opinion that a site is an alt right friendly den of social iniquity, Google, the nearest-monopoly of all of 'em, is only too happy to throttle their search results.
