Nick has nothing to lose. Everyone knows he's trash on the mic, including him. He only stands to gain from the exposure and put his artists on.
His one strategic blunder was responding via rap at all. After all Em's goofy ass is the battle trained rapper and more skilled emcee. So there's no way Nick is winning the 'rap contest' portion of this dispute.
He shoulda just let his more skilled, affiliated acts handle the bars and get on his J. Prince and just talk some shit over a beat in between verses.
Cuz even though I'm rootin for him, I'm not tryna hear his trash raps either.
