He's one of the top most UX experts in tech for the last few decades, and as he has now retired he freely offers his time helping with UX in open source. He has no commercial motivations whatsoever, he's driven by the fact (and yes, it's a fact) that many open source projects don't have access to competent UX resources while commerical companies do.
He's not some AI proponent - he's one of the persons actively working with the Mastodon team on making our UX better.
