Until it does happen…
The situation here is also a bit different from moderating "a public website".
Noone's saying that everyone should have the right to have their presence and reach amplified.
But these bans on LinkedIn and GitHub apply to the entire account and the entire identity of the user, meaning, you could now be precluded from doing the most basic things compared to all of your peers.
LinkedIn ban precludes you from connecting to employers at in-person events unlike every other attendee. GitHub precludes you from working at any startup that uses GitHub in their workflow.
Plus, as the example shows, causing any sort of disruption isn't even a prerequisite to getting banned by these services.
It's about the employees having an inverse incentive, to take actions just for the sake of it.
It's actually exactly about this attitude that somehow noone has the right to be on the platform, which, in turn, makes it easy to justify these forms of deplatforming and censorship, and the resulting self-censorship, too.
I don't think that's necessarily true.
I think large providers would like to say that, but at the scales of cash involved, I think the burden of saying "no we can't be held accountable for what we do, get lost" should be much higher.
If a significant fraction of people are relying on their personal networks to find jobs, even if they're not working in a job where presenting a public face is a key component, then being cut out of large-scale social networking is no longer divorced from your professional life, it's a necessary service.
