> If it is a public square, then it is so because the majority of people choose to use it because of the controls and filtering and exclusion of "undesirables". If it's a company with a reach in billions that's because it provides, in its current form including filtering, a service that is valued (in attention time, if not dollars) by its users.

I don't think that's the case, honestly, it's a pretty explanation, but people aren't on these platforms for that, they're on these platforms because it's where come critical mass was hit, and from that tipping point these apparati were ossified. And as they became a nucleation point for all of this, their volume grew, and with that so did the content - which is crucial if content generation on the platform respects the 1% rule. And that new content is what creates the feedback loop, which is also ostensibly directly proportional with the size viola, positive feedback loop to some arbitrary user saturation point.

For example, some Youtubers have discussed it, but relocation would be a huge investment, and quite a bit of their data would be lost because they don't have archives that run back to the inception of the channel. In much the same way reputation, clout, followers and et cetera would actually go through translation losses as someone or some company transitioned from A to B, and servicing two platforms is more difficult than one (which will likely not be lucrative). It's a huge moat.

What is the actual end of this? You're not eliminating these people, nor their opinions. You're alienating them. The best case scenario is a dialectic which ultimately causes them to question their viewpoint, not to reinforce it by arbitrarily castigating them and exiling them from the public discourse. In the case where some platform does remove them, they'll find another with less criticism - an echochamber - which, to wit, only stands to exacerbate the problem.

It seems less about some class of deplorables and more about their observers. As to their rationale, the primary motive I suspect, is profit via demographic sprawl, not some humanitarian concern. And this can be imputed to the individual as much as the corporation or institution. By my reckoning this is a hazard in and of itself because it's purely superficial and thus both misguided and misapprehended - one half of that becoming concrete realizations of naive intervention and the other setting some anti-human benchmark that doesn't actually make sense. And of course the feedback people and institutions read is from some extremely small proportion of the population so it's already set up for a form of extremity by default.

And is anybody really defending ultrawealthy individuals in such a way? I don't know anybody that really condones the idea that wealth should be able to have a hard and cheap translation into hard power as it does in this instance. And there's also the fact that Twitter is a legal fiction, whose foundation is rooted in not just the concepts of property rights outlined and enforced by the US Government, but additionally is accessed and deployed through a heavily subsidized technology that was previously publicly owned and developed with taxpayer dollars. The Kochs are private persons, period.
