Both of these are relevant to his removal back then, but how are they relevant now?
> assure the best outcome for the FSF, which IMO didn't include having a leader who made such statements.
Ok, he's no longer leading the FSF and the recent development does not aim to change that. Why is this (reasonable-at-the-time, imo) opinion relevant now?
> I've reached the conclusion that it's not that he's unable to understand, he's just unwilling to change his mind.
Did he change his mind now? Has he repented? Atoned? The 2019 pieces are not going to take this into account.
It is certainly possible that between 2019 and now that he is no longer "unwilling to change his mind." (I think that's more important than whether he "repented"/"atoned"; I'm not looking for a YouTube apology video, I'm looking for an effective leader.) But a) given that complaints about his leadership approach had been around for decades, it's a priori unlikely that anything changed in the last year and a half without further information, b) his announcement didn't say anything about reflecting on why he stepped down, he just said he's back and isn't planning on stepping down again, and c) he's continued leading the GNU Project, which the FSF provides organizational stewardship for, everything points to nothing having changed.
We don't know why the FSF put him back on the board - we don't know if the board asked or he asked. We don't know whether they took any of the above into account. We don't know what his role on the board is. The only statement the FSF made is that one tweet.
(And, in any case, being a member of the FSF board is a leadership role.)
I agree that the open letter doesn't go into full detail about why the authors of the letter believe that no meaningful change has happened, but I think they are justified in believing it.
