I think he's a positive force as far as awareness goes. He will display ways of making windows, ios or google android safe because he is trying to appeal to a very broad audience. The peoole he wants to reach are mainly non technical.
As for the bad, he has a "leave me alone and don't make me pay taxes" kind of vibe going for him, almost like an ancap. That is not the focus of his talks though, just heard him mention here and there. That kind of stance is common among tech media creators though, and I never saw him promoting that.
For me, he actually pushed me towards degoogling my life. Overall, he touches on lots of privacy - related topics and I feel that he is being 100% honest. Sure, he may be wrong in some cases, but it's just being wrong, not malice.
He is stupidly stubborn though.
