No ones trying to destroy Morrissey's career, or hopes he never sells another ticket. Okay, maybe three people. Still, to even imagine that there is enough interest in Morrissey for any of this to matter, means you're likely living in a social media bubble.
Then again, he could probably sell even more tickets if he stopped sounding like an edgy, YouTube conserva-teen trapped in an elderly man's body. His core audience is not the alt-right.
What all of this has done is put a stamp on his legacy, and made the NME look like hard-hitting investigative journalists ahead of their time. It's safe to assume that's something that even they never aspired to.
He's helping these media outlets when he does this, and I'm sure he hopes for a return on investment, but let's not forget that these media outlets love when he pops off. They're benefiting from it.
Ultimately, I think Morrissey's strategy has always been to be divisive. He rejects people before they can reject him. He never grew out of it as a response to adolescent trauma. Adults are supposed to be stronger than that, but Morrissey has no one to be an adult for. It's not something he has to consider.
