Always open raise or fold, never open limp? Expert opinions

[mrwatson23]

Ray Zee offered this gem in a thread below: "They taught a gorilla how to play golf. He hit the ball 400 yards right down the middle. Tiger Woods was very worried until he saw him hit his putt 100 yards."

I take this to mean that Ray doesn't agree with the open raise or fold, never open limp strategy. However here are a few players who do advocate this pre-flop strategy: Howard Lederer (considered by many to be the best limit hold'em player on earth), Tom Weideman (mid to high limit pro, Physics PhD, genius), Chris Ferguson (WSOP champ, game theory expert, the only strictly tournament pro Sklansky says would crush cash games), and Abdul Jalib (80-160 pro, computer science guy). What makes these guys wrong?
