The two main things that are causing the hitting issues are 1) all-or-nothing, extreme launch angle, don't care if they strikeout approach, and 2) pitchers' non-fastball pitches. To the second point, we look at how fast fastballs are now and think that's why pitchers are so dominant. It's actually their other pitches. When guys are throwing cutters at 96 MPH, sliders at 95 MPH, and wiffle ball changeups at 91 MPH, hitters have no chance.
