I been thinking, and I'd say there were likely cordial talks behind the scenes between Prince and Puff before this "leaked."
He probably spoke to Puff in private beforehand and gave a heads that he was putting out the message, and let him know its just for show. This way Prince still looks good in front of Drake and has his trust as a protector. They likely even agreed on someone that, if it came down to it, it would be cool to have beat down or whatever else, so long as it wouldn't affect Puff's money (i.e.- an artist who's marketability would drop as a result.) Again, at the end of the day that's what this is all about, money. Puff doesn't actually "care" about his people anyway, just their usefulness. In the end they discussed a small compensation, which could be any number of things, for Puff to just sit back (he doesn't have a tough rep to protect and no one is gonna stop fucking with him business-wise because of this so that's all he has to do: nothing.)
Then look at the rest of who he addresses and what was said:
Suge he doesn't threaten, he just welcomes whatever he might bring. Suge is locked up and likely never coming out, so he doesn't have time to care about this shit either way.
Wayne he talks down on, but Wayne is a nobody in the sense that the rest of these cats are somebodies. He's a nonfactor in the sense of making moves.
Baby and Slim he just goes on record as saying they owe him. He's already talking them to court, right? Again, it doesn't amount to anything anyway.
After a second listening, assuming Prince gave Puff the head's up, this message really wasn't anything but a reassurance for Drake that he has his back. It was basically just a ruse to get Drake and the public to think there's something brewing when there really isn't. Why go to war when that fucks up the money? Much better to put on a show for the people then to actually get into it.
