I don't see anyone trying to take away his achievement. The report and most commenters even recognize his contribution.
Also this goes more deeply than "not liking them", he has some morally reprehensible views. I admit I haven't read the whole report, but I have seen some of the things it touches on in the past and it's pretty damning.

I gave him credit for that while also saying we shouldn't platform him or give him attention until and unless he recants and / or apologizes. Just like the report says.

I think, this is what contemporary cancel culture usually tries to do.

I also think, that this is wrong on most occasions. Maybe sometimes possible damage warrants cancelling someone, I don't know
