I agree with this, to a point. Cleaning or snatching with form that's "good enough" to get the weight from Point A to Point B without doing harm will still build strength and muscle for the majority of lifters, even if it isn't textbook-perfect technique.
Like every other exercise, it's never a bad thing to polish technique. But, as I said, for most people, "good enough" form will be good enough.
I think a lot of people are unnecessarily intimidated by cleans and snatches, when they'd be served just as well treating them like other big, compound lifts (deadlifts, squats, overhead pressing, etc.)
Start with an appropriate weight and progress according to results and goals, letting general technique improve with experience.
