The guy does a lot to push prevention education. I also read an article a month or two ago where he's helping design a brace that may help prevent the injury. So I can't really call him cut first, ask questions later.
I think there are two big factors. #1 is year-round ball from a yoing age. #2 is that pitchers don't want to pitch in pain when this surgery is available. In past years, i think a lot of guys pushed thru the discomfort of partial tears. Now they opt for the surgery, get paid while rehabbing, and come back with the elbow feeling good.
