Why are baseball pitchers having an increasingly difficult time staying healthy?

Because there's No Free Lunch.

The same tricks and shortcuts that are — pretty much universally, now — being used to enable pitchers to throw harder work by overloading the pitching arm.

That works.

For a while.

However, just as running a car engine past the red line for too long will cause damage, so too will running a pitching arm past its red line.

Thus the epidemic.
