What you are mentioning regarding the case of Stallman’s cancelling is the same pattern I have seen applied against every other voice that has a dissenting opinion of the current culture that dominates social media.
No. Spacey, Weinstein, and Epstein, to name a few, felt the opposite of manufactured. Repressed? Those stories took years, or decades to break, even with high profile advocates.
Now, you might say that they didn't have a "dissenting opinion of the social media culture" - but their actions would show otherwise.
None of those characters were individuals who were cancelled based on their opinions against the dominant culture in social media.
Also, they weren’t cancelled, they got charged with one or multiple felonies, which is different, and there are plenty of apologists for their behavior.
For example, this was a real tweet that got taken down.
