nobody:

The inherent artistic dead-end of punk as a genre was made obvious by Joe Jackson, Elvis Costello, XTC and countless others who got their start with the stripped down punk era, who once they were established, released music that was much more artfully produced and arranged. And it's THAT work that most of these artists are remembered for. Your assertion that other forms of rock were subservient to punk for more than a coule of years is wrong. Punk sales have never been as big as the more mainstream genres of rock.

Yes, a lot of PiL sounded nothing like punk because it was basically progrock. It was "experimental" to someone weaned on punk, but they were just rehashing tried and true prog/spacerock formulas from the early 70s. Your assertion that PiL's sound was possible only with "punk's explosion and aftermath" is simply wrong. It's just an obvious fact to anyone that knows prog.

My point being, while The Ramones DID change the landscape of rock music, it was a step backwards for it. Many of the artists who got their start with the punk scene turned their backs on it as soon as they were able to.

The Ramones didn't, and while it could be argued they they remained "true to their roots", I personally think they were simply a one trick pony, a novelty act who couldn't shed their whole "onetwothreefour", fish-heads and leather jacket schtick because they were simply incapable of doing anything else.
