I think Curse contacted him about potentially dropping him. I think the reason it happened recently is from the Google+ spam issue (#1) and the resulting strike(s) he got from unprivating all of his videos (#2). That community strike he got (plus other video reports he almost certainly got) likely put him on Curse's radar enough that due to the recent MCN rule changes (
https://www.polygon.com/2018/4/23/1...n-multi-channel-network-creators-monetization) they are considering dropping him. Here's the logic:
"I did nothing wrong. I've been told it's nothing I did wrong. I can't fix it." -- He blames the unprivating issue and resultant strike on Youtube/Google, despite the fact that it WAS his fault. In his little world, though, he truly believes he did nothing wrong. The 2nd statement would follow if the MCN rep used nice language that was something like "Sorry to do this, but with the new rule changes, we might have to...". And the 3rd statement is obvious--it's the MCN's decision.
This fits with basically everything else he said about it: 1) it's not taxes, but it does affect his finances (he'd be more open to strikes, content ID claims, and so on, presumably, in addition to any effects on his CPM rate); 2) he wouldn't lose his channel as a direct result.
It's also worth noting that Curse is not currently accepting new applications to join them either, which suggests that they're worried about something. I think it's more likely that he's facing getting dropped again, which won't rattle him as much since it's happened before and thus he's not totally freaking out but
is sad about it, than being informed of a potential lawsuit, which is
not something he's familiar with and would, in my opinion, result in a freakout. He also wouldn't take the chance of actually talking about getting dropped for fear of saying something to actually make it happen (a la Machinima) or get a torrent of people contacting Curse with incriminating videos.
