I think it's purely based on numbers. Ralph does not bring anything to Odysee.
Scanning through other channels. He's got decent numbers against quite a few of them but it's nothing mind blowing. Videos range from 600 views to a maximum of 16k in the last few months. Lots in the 1000-3000 views range which is certainly above average there. Even compared to Shadiversity (who mainly is on YouTube) he has similar views for many vids.
So, is he a "big deal" on Odysee? Yes. Is he big enough for an exclusivity deal? No.
What are exclusivity deals for? Like I said last time, it's for poaching someone like Ninja. You give an exclusivity deal to someone who isn't using your service to draw them across and to bring their audience with them. Ralph isn't some big streamer on YouTube to poach, he's banned there. He's not some high level Twitch streamer with 20k viewers. He streams on Odysee and Cozy. I doubt Odysee looks at Cozy as competition to poach off.
So, yeah. In my opinion it's something he said to pretend to have draw strength. He wanted to seem like a big dog, because Odysee still won't come out and say "Yeah, he's lying" about a contract.
