I do not think that's what it means, I think you are being negative. I think M (I do think it's him who wrote that) was just taking the piss "f*** me, they are letting me on a cover again, who would have thunk it" . I mean they tried to cancel him big time. This is a hint that the corner has turned.
His career isn't in the toilet, at all. His new lp has iggy on it, He had a successful Vegas run and UK tour and his shows in the states have been awesome.
It's true he lost a f*** load of fans it's true he isn't considered the icon he once was, he doesn't have the social standing he once did but he is still iconic and can still make bank. He can turn it around still.
I think the Simpsons episode, as cruel as it was, has got him back on track.
I think he sat down to watch it, proud that an iconic American and cultural institution had made a show around him, with a Hollywood A lister as the voice He would have expected some gentle piss take , but probably thought it was gonna be a blast and help his career. Then when he saw what they made him out to be. how much they ripped into him and how much truth there was in there. I think it made him reflect and get his ass in gear. Thats why he now looks great, his shows are f***ing awesome again and there has been no mention of UKIP or For Britain.
