I think one reason, almost never acknowledged by golfers themselves, is that firm and natural and bouncy and bumpy is a lot harder to play off of than lush, soft, green and monochrome, especially for the average golfer who is not actually very good at the game -- or, more importantly, not nearly as good as he'd like to think he is.
(You know the type: by the third hole, after starting double-double, we're saying things like "I don't know what's going on today, yesterday I was hitting it pure, but now it's like something's off, I don't know....and this turf, this is lousy, I mean, how are you supposed to play off this...and then I finally hit a good drive, right in the middle, and what do I get: the ball's 3 inches below my feet and right in this patchy bit of crap".)
As I say: rare is the adult male who will say "I'm not good enough to play that course, especially if the wind is blowing". It's much easier on the ego to say "That place is a cow paddock - that's not golf" instead.
Over the years, reading Sean A's many profiles of GB&I courses, it became clear to me that I've frequently hit the 'like' button on the quiet, gentle, fairly straight-ahead English inland courses, e.g. Sherwood Forest, much more often than I have on the raw/wild and twisting coastal courses of Ireland and Wales.
The truth is, even looking at those courses kind of scares me, i.e. with the blind/semi-blind shots I'm sure I wouldn't know *where* to hit it, and with the uneven and bumpy ground and the likely wind I'm pretty sure I wouldn't know *how* to hit it.
