He effectively pretended to be dumb. And that included using the wrong "you're" and very simple dialects of English and mannerisms which he thought could potentially be seen as disparaging some groups.

I think it was so generic and so clearly a joke it would be insane to pretend it was making fun of a group that existed in real life.

For reference in the talk he also listed strongly typed languages as "weekly typed", static as dynamic, and had a MacBook on stage display a BSOD.

The talk was comedic genius and a fun tongue in cheek commentary on the industry in 8 minutes. But it has been deemed to dangerous to society to be allowed to exist.
