A group of people including Drew DeVault are trying to cancel RMS again, basing their claims on ancient misinterpreted quotes. Stallman may be controversial, but these activists are just acid for the entire Free Software movement.
I believe so but the video presenter is right in two aspects, the first, this is not anything new, RMS was even left out from his position after the influential banning movement against him got stronger some time back, and them that got reverted. At their time there was an open letter demanding RMS removal and the entire FSF board as well after re-electing him, and also a reaction open letter supporting RMS. There are also posts like the debunking of those allegations. As you can see this is not new, and the recurrent nature of these allegations really make one to think about their true intentions.
Something to keep in mind there are some recent and not so recent allegations from one public and influential blog, for example the FSF is dying, RMS on sex and his latest allegations regarding RMS "neurodivergence". Perhaps these examples plus several additional ones in the same blog make the blogger one possible suspect in the video.
And the second aspect I believe the video presenter is right about, is that after reading RMS' several posts, the allegations against him, and the debunking of those allegations, plus all that movement attempting his banning, it's clear that one can not be as naive to pretend this is just a personal attack, there's more to it in all this. The reputation of the FSF gets really hurt. What gets in people's mind is that the FSF, GNU, the copyleft in full defense of the user freedoms on software is no longer relevant and even polluted. People forget that in the name of supposedly good causes, a lot of damage has been done through out history, and this hating/banning/canceling movements do more harm than whatever good intentions might show up in the surface, so be cautious about them in general.
