Read the many, lengthy direct quotes from his writing in https://www.theverge.com/2021/5/12/22432909/apple-petition-h....
This is a guy who has made a writing/speaking career of knowingly saying crassly offensive and, at best, childishly naughty things about entire classes of people he would be managing at Apple (or anywhere else). He's a professional troll. It's not like someone dug up a single reddit post of his he made when he was in high school.
It's a genuine mystery to me how he got hired for any management job in the first place.
