Well there's a million ways you can interpret that data. Apple usually makes very opinionated stuff ("this is how it works and this is how you're going to use it"). Autistic folks tend to do have big issues with that sort of stuff, so it's only natural they'll gravitate to something else where they can use it whoever they feel is better.

And women in general have been pushed away from IT for a few decades due to how they're treated in those groups, so it's only natural they'll be underrepresented among Linux users.
