Autism affects how senses are processed, and taste is a sense - some autistic people don’t want things that are strong or that vary a lot, preferring consistency instead.
With that being said, it’s not a universal thing, different people are affected differently.
It’s nice to see someone who used to be so deep into the Adobe ecosystem was finally able to switch over. I hear that it used to be considered practically impossible unless you weren’t already in very deep. As a result, many people simply said they wouldn’t consider Linux unless Adobe products supported Linux.
The fact that he’s proven Adobe doesn’t have a stranglehold anymore gives me hope that we’ll be seeing more and more people migrating as software supporting Linux gets better.
