Nobody cares outside of some rap nerds. It had no impact on Drake's career and it's time for people to be honest. In 2001, Hov was a much bigger rapper than Nas. And yet you can literally trace the impact on Ether in terms of street reaction, Hov's reaction, RADIO reaction, etc. Not to mention it revived Nas' career commercially.
I'd argue the Meek thing hurt Drake more because at least he revealed something tangible - ghostwriting. Which should hurt Drake's reputation as an MC. What did Pusha hurt or damage?
