What happened to Adrive?

I haven't watched his content in a long time, but I used to when I was a kid. So out of curiosity, I went to check out his channel and it's very different than when I stopped watching. He's posting schedule doesn't seem to be consistent anymore, there's more negative comments under his videos, and his subscriber count is under a million when I thought he hit 1 mil at some point? I found out he's working on a card game rn so he doesn't have the schedule he used to, so that explains the sporadic uploads, but to lose subscribers and have folks be more openly negatively about him? Did something happen or did his channel just start to fall off?
