So, in the end, RMS lecture in 2023 was cancelled because of a controversy that happened 2 years ago that since then has been solved?

IMO it just looks bad for EPFL if they decided to cancel the lecture based solely on this. If they knew about it, then why tell RMS he could hold a lecture only for them to cancel it on the last minute to bring back this topic again?

Exaggerating a bit but this is like inviting Linus Torvalds for a lecture, then cancelling it at the last minute because of his previous attitude towards the Linux git repository.

EDIT: I just read their response and they are boldly assuming that RMS would divert the topic from free software and open source during his lecture, which I find it very difficult to do so, unless asked, given what I know of his persona.
