Exactly.
Some people here have disagreed with me, but I truly they thought they were getting a legal show. I think they were (unstandably) impressed with the view numbers he was pulling in during live trial coverage, and wanted in on that action. Same with the Superchat figures he got during Vic. During Weeb Wars, he was one of the top Superchat earners on YouTube. Most of the content he did pre-Rumble was legal stuff.
Did they renew them? Will they renew him? I dunno, but if they did/will renew him, I don't think it's sustainable with his current mind rot and work ethic. Rumble's stock is looking pretty rough.
This might be a controversial point, but I almost want to say YouTube's rules helped Nick overall. It forced him to avoid acting like a complete jackass, and to play to his strengths (even if, in hindsight, he's not a very good lawyer). Being able to operate in a more laissez faire environment seems to have invited complacency and a belief his personality was more important than subject matter.
