I don't really think this is much of a diss. All he is saying to Pusha T, Meek Mill, etc. is he wants to be better than them. It's the equivalent of LeBron saying "yeah I like Melo, Durant, and CP3, but I wanna be better than them." Isn't that what he's supposed to say?
Also, I'd be more offended if I wasn't mentioned in his verse. That means you aren't even relevant.
