It's a commercial act, the 'punk' costumes carefully chosen for the right signalling, by a couple of middle class kids. What's with this idea that your taste in music must spring from the purest and rawest authenticity, preferably (in no particular order) poor, rebellious, substance abusing, ethnic, and so on. Leading to all these musical acts styling themselves like that.

The Ramones were sellouts and posers, just like most bands. Wearing them on a t-shirt to signal 'punk', the joke's on you. It's an "industry of cool", like Jack Black's character says in Almost Famous.
