Look at BitChute and other small video sites now that YouTube has been deplatforming trolls and crazies. They are full of toxic waste. BitChute now gets called “poopchute.”
4chan is considered toxic waste. Old Youtube was full of toxic. Old Tumblr was toxic waste.
Those are / were home to the most creative communities.
Now? New centralized media is starting to look a lot like old media: standardized, no spice, boring. Perfect for a protestant society.
Of course it was. The premise that racists wouldn't take advantage of communities which let them communicate openly and gave them the plausible deniability of "irony" while doing so is absurd. Why wouldn't they, when the community "mocks" them by acting just like them, reinforcing their beliefs, spreading their gospel and making them feel as at home as possible?
I mean, it's not exactly a scathing rebuke, is it?
In many cases these smaller sites were created specifically to cater to those "obnoxious trolls, crackpots, and hate mongers" as a "free speech/censorship resistant" alternative to the mainstream. BitChute's selling point is serving content which would be banned on YouTube - obviously that's what they get. If they or similar sites are victims of anything, it's their own success.
The only argument you need to make for a competitor to make sense is "<Platform X> isn't perfect." That's accurate for all of them. A good competitor will have all the same challenges a 'bad' competitor would.
