He's got autism, which he has discussed openly on camera and I think wrote about in his book.

I don't think that's what OP was talking about.

For the first year or so of his rise Dave finished each videos by "I'm only in this for the subs and likes" and had monetization turned off.

Now he ends with "I'm mostly in it for the subs and likes" and has monetization turned on.

He's also removed his claim that all profits from his book and channel go to autism research.

Nothing wrong with making money from your work but it does show a change of focus.
