That's possible. I admit I haven't been keeping up, and my knowledge of squatting stems mostly from the 1990s, when I was a student.
I still think it's a very pragmatic way to fight real estate speculation. But my impression is that Amsterdam doesn't have a big problem with buildings sitting empty, so if squatting is illegal again, I guess they've found a different way to prevent it? I have no idea what that is, though.
