Painters tape taking paint off wall - whose fault and how to fix?

Had walls professionally painted a couple of weeks ago, then painted trim myself. (Aside: I have much more respect now for why trim painting is a whole thing…) Walls had been primed by contractor following renovations, so painters only did paint, not priming.

Put painters tape on the walls to do the trim. Pulled the tape and noticed in some places the paint from the walls was coming off with the tape - sometimes just the new paint, sometimes down to the drywall. In some cases there’s a clear edge so more of it will flake off if I start picking.

I pulled the tape at an angle, ran a razor first, used good tape (frog tape, the green one). Wall paint was BM Regal Select. Trim paint had no issues with the tape, only the stuff on the wall.

Two questions: 1) whose fault is this, probably? Mine for taping badly (or too soon?), the painters for doing a bad job somehow, the contractors for priming poorly? 2) more importantly, what’s the best way to fix this? There are a lot of these spots all over, the photos show the worst ones but there are plenty more.
