Why do you think the second case happened? He resigned from a prestigious position on his own terms. If I expected anyone to tell straight "I've been forced to resign" or "I've been fired due to politics", it would be RMS. He didn't, and nobody seems to be preventing him to take part in public life - as evidenced by the number of posts, there's a number of people who still want to work with him.
He was witch-hunted on the internet by a serial witch-hunter, some "journalists" who lack basic reading comprehension and the lynch mob that ensured. It's naive to believe he resigned voluntarily. He was pressured into it, probably believed the witch-hunters, lynchmobgoers and finger pointers to a certain degree that he indeed is evil, resigned to protect what he created and therefore was nice enough to not shit all over the institutions he created on his way out.
His reputation was set on fire and burned to the ground, he was expelled from his life's work, might even have become homeless as a direct result, and most of the people he considered friends or friendly vanished over night (tho, some remain as you pointed out, but decidedly few) destroying most of his social (support) network.
He built a global movement challenging people publically and he's happy to semi-publically state his opinions about sexual assault at the worst possible time, but he will stay silent about pressure to step down to be nice? I'm sorry, but I just don't believe that.
Reading your link, I don't find anything troubling. He says the term is too ambiguous and it makes it easy to (potentially maliciously) misrepresent someone's acts.
If you find anything else he's said troubling please provide me some references as I'm trying to read anything that may help me to understand this episode. (I've already read about his former and present opinions on paedophilia)
