Pretty much never should have screwed anything into the subfloor, regardless of screws long enough to go through the flooring. That’s entirely wrong. If it were screwed into the joists, or blocking between joists, this could not have happened
I wasn’t implying sinister, but utter incompetence. Too long of screws is an “oops” but this is like attaching a cabinet to the “wet wall” and blaming too long screws for the leaking pipe

Its a simple case of bad carpentry, it doesn’t have to be sinister.
