I think the jokes he made about Louis CK and Kevin Hart point to Dave's motivation in this special.
I think he looks at what Kev and Louie lost (Oscars gig, TV show, sponsors, [White] fan adoration etc.) and those are things Dave doesn't want in the first place, so he just said "fukk it" and decided he might as well say what he wants to say, because the things "Cancel Culture" can take from you are things Dave doesn't have or won't mind losing.
They can never take stand-up from you, and if that's all you really want, might as well go in.
"They" can come for the King, but their bullets ain't got shyt to aim at.
