Actually, right of center content brings them lots of viewers even when it's not as violent as Antifa rhetoric.
Well, to be honest, I don't really follow any of them that unrealistically push the boundaries. Of course everyone has heard about Alex Jones and I'm not a fan of his but he's the best example of deplatforming I know of. I have heard of the Milo guy but never paid much attention. As far as people I think that have been treated unfairly my best examples are Steven Crowder whom they've only demonitized and McInnes whom they (YouTube) seems to have let back on. But I do feel that social media publishing is going to have to be addressed legislatively to preserve freedom of speech. If social media publishers don't like it, they are free to close their operations.
Seriously, though, boycotts (over speech) are so dumb. A bunch of people that either would never have bought the product anyway or will continue to do so even though they say they won't actually influencing companies' policies is hilariously dumb.
