I posted my own comment, but every time Stallman comes up, this is what I refer people to: https://drewdevault.com/2023/11/25/2023-11-26-RMS-on-sex.html
As you said, these are not his “early views”, but a continuing and shifting pattern. You can read his own blog posts and its all there.
What part of how he’s been treated? Nobody is making fun of him for being neurodivergent and picking his toes in public. Its gross, but ultimately not harmful. People have problems with his inability to understand how his comments about sex with minors are not appropriate either. There’s a big gap between these two things and if you fall into it, you’re probably okay.
