Well, they often approach the outdoors with a more amusement oriented and less spiritual approach. Outdoors as playground vs. outdoors as temple. Not that that approach is inherently bad, but it does change things - more emphasis on bolts, mechanized access, etc. Since I don't particularly like mechanized access it's hard for me to say "so what".
Climbing isn't alone - similar things are taking place in skiing (bile skiing), surfing (tow-in) and kayaking (waterpark/wavesurfing) to name a few. The locus of interest has shifted from a few long backcountry trips to many more short frontcountry trips, and daylong amusement.
