It's fine to think this will never happen to you because you're not important enough, or not controversial enough, or have the most mainstream ideas that would guarantee that you won't be a target…

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.
