Autism isn't an excuse for bad behavior. It can explain some bad behavior, but that bad behavior cannot continue over decades; it must be dealt with in some manner.
I cannot believe people keep defending him given the accounts of what he's actually done (assuming you believe the accounts). What about the women who have been creeped out or harassed by him, or who have left the field because of him? Don't they get any consideration?
As Matthew Garrett has pointed out (through personal experience with RMS), "the problem isn't that he's unable to understand, the problem is that he's unwilling to"[0]. So I don't buy the "because autism" line here.
