I think folks are reacting to allegations of sexual assault/rape (a few different women, including a minor).

Then there is the fact that his comeback tour is with Five Finger Death Punch, a band that glorifies police and demonizes mask wearers in their lyrics.

Well, he's basically a rapist and abuser. The accusations are a bit more complicated than that, and even a bit worse, but there's really no doubt at all that they're true. So a lot of people outright hate him, and will reflexively reject any posting of his music, especially a new track that's on a platform that would generate income for him.

Musically, that's a matter of opinion. It's definitely the same style of music for sure. My take is that it's watered down and uninspired, this particular track. Pretty much phoning it in. If you like the track, there's nothing wrong with that, all musical preferences are subjective. It just doesn't work for me. I can't speak for anyone else in that respect.

You're very out of the loop for all of this. I have never listened to him and never cared, and generally stay away from celebrity gossip and even for me it's been hard to miss everything about all the shit he's done and is accused of having done. It's widely known he's a piece of shit.
