I think people who criticise rock and pop bassists have difficulty understanding the meaning of the word genre.
Colin Greenwood is a walking textbook of pop/rock style and plays what is right for each song that he records, down to a specific string, bass and amp.
To criticise him for not playing like a fusion player (or Mick from Supergrass who was half of one of the most dynamic rhythm sections of the britpop era) is nonsensical.
I would expect that most chopmeister bassists would produce ersatz mushy session drivel if ever called upon to play in any of the bands mentioned in this thread. It's simply not a genre they understand.
Also, just because something sounds easy doesn't mean it is.
