I see what you mean.
I don't know much of his other statements but I thought he was talking about these nu-rockkids that jump around on mtv and stuff without having any skills whatsoever...
Apart from that I think they had some solid songs, I don't care if these are radio friendly, it WAS a fun band that had an impact on rock history but you shouldn't take any "rock statement" too seriously... I'm sure you can ask any old rock band, Sabbath, Maiden and so forth and they'll all say more or less the same, that their music was true rock and todays music is commercial blabla.
I know it's hard to enjoy music once you know what the behind it think (think Manowar here...) but it shouldn't get in the way.
What most people don't get is that rock at that days was kind of a revolution whilst now it's just another style of music using real instruments (most of the time), it doesn't have the expression and meaning the way it had it back then because people try to progress, that doesn't make it less enjoyable.
I believe if you can enjoy "both worlds" it'll make things like that much easier to understand.
I mean....come on... look at Metallica for example. Truly a remarkable history but yet they made sooo many bullshit statements it could make one sick.
