I've read it as a compliment about the band. Other's will read it as relief that they ended when they did.
Steve Jones and John Lydon tell the truth. When they toured a couple of years ago they said they had no problem doing it, but they were very clear they were doing it for the money. I think Jones and Lydon wouldn't have an issue with U2, but they would have an issue with the pretentiousness of Bono... I used to get annoyed when people hassled Bono... but I'm afraid to say he has turned into what he was accused of. His stuff that he does just seems so calculated and cringeful... which reached peak-cringe during th Paris I&E DVD of the fans getting on stage, and then simply was beyond embarrasment with that weird performance during City of Blinding Lights.
Just play the music, don't try so hard... it looks silly.
So Jones, I think, if that had been explored further would have likely said that ending up like U2 would be both a good thing to strive for and a bad thing based on the pretentious behaviour of Bono (and I'm not talking about the extracurricular stuff he does). By all things holy, what's with 30 people on a stage wearing a mask during Walk On?
