There was about a decade's gap where he could have changed his opinion.
In fact, during the MIT CSAIL scandal it's apparent that he did, since he noted that Epstein's victims were absolutely coerced into pretending they were willing when they were not (which certain news outlets I will not name spun into "stallman says they were willing"), and he also said Epstein is not described harshly enough.
Of course, you're free to dislike him or even disbelieve what I just said, but you can't deny that what he says about software is damn near prophecy.
