The thing is, deplatforming works. Banning far-right actors has drastically reduced the reach of their messages [1]. Personally, I see this as a Good Thing, simply because of the potential that spreading hate has to escalate to actual, real-world violence, from murders like in Charlottesville to an outright attempt at instigating a coup.
At every sudo prompt, we get the warning "With great power comes great responsibility" - for good reasons. It's the same with running a social network connecting literally billions of people... those operating them have great power by the sheer market size of their platforms, and a huge responsibility for just how much of the bad side of humanity can be empowered by them. Whatsapp, for example, was directly linked to dozens of murders and severe injuries after lies and propaganda led to lynch mobs [2][3][4].
