Do you have a source of him confirming it? Genuinely curious.
I'm just going off of his interview with Joe Rogan.

I thought you meant that he went on record saying something like "I'm perpetuating gender stereotypes".
Instead, it looks like he's just confirmed that Google thought he was perpetuating gender stereotypes, and that's what he was fired for, which is no surprise.
