For strictly musical and content reasons? Nah. Not even close. I do think Puff going OD looping 80s hits for the beat and taking a hook from another hit hurt the industry. In that it drove publishing percentages for the original writers and the price of clearing samples through the roof. Which led to the cheap Casio beats of the late 90s that permanently watered down the NY sound. If you got to pay big money up front for clearances and give away 90% of your royalties to release the track, at some point it don't make business sense to sample.
You can also say he was a major factor, either direct or indirect, in Pac and BIG murders which did incalculable damage to hip hop musically and culturally. Dude is a crook, a psychopath and a sexual deviant but the music industry always been full of all those types.
But strictly music? When he was relevant, Puff only pushed crazy talented artists for the most part. 94-03 Bad Boy had many classic tracks, albums and that 94-97 era especially is still some of the most fun to listen to hip hop music ever made while still being nice lyrically. He still promoted the standard that rappers need to have bars. Even himself, he couldn't rap very well but at least used elite writers and ain't pretend he was a real rapper.
The anti-lyricism, pro-ignorance movements that was not only accepted but embraced by the audience was way more harmful than Bad Boy's extravagance and materialism. And all the notable Bad Boy albums had more grounded subject matter to balance the party shyt and bravado, even No Way Out.
