Was he canceled?

From what I understand, Stallman had several role at FSF. One of them was spokesperson, which is basically Public Relationship. Then, he made several actions showing that he does not understand the basis or does not have the skills to work in PR. So, we was asked to step down from this position.

If you hire a front-end developer and later discover that they are not able to do the basis of programming, are you "canceling" the developer if you decide to not continue to work with them because they are not what you need for the job?

(As for MIT, apparently, it's based on a series of incidents. Again, his work requirement included skills that would imply he would not have done those mistakes. Positions a universities obviously includes as requirement basic skills in knowledge communication and ability to work with pairs, that's what universities are supposed to do.)
