This could be the case, especially since several satellite operators are starting to address the problem. As you noted the other day, India took care of one of their satellites so that it would not become or create debris: https://behindtheblack.com/behind-the-black/points-of-information/isro-successfully-de-orbits-defunct-satellite/

On the other hand, most of the constellations that are going up now, the ones that get the most complaints about this, are going into orbits that don’t currently affect the ISS. If these constellations start having satellites that die before they can deorbit themselves, then there could be some difficulty with a growing amount of space junk. I suspect that, due to such premature deaths, the operators of these constellations will be major customers for the budding industry of space-junk removal.

I think that space-traffic management will find a way to make things work in space. The first step was to track objects so that living satellites could maneuver out of the way of the dead flotsam. The second step has been to reduce the flotsam by ensuring satellites and upper stages deorbit themselves at the end of their lives. There is discussion in the industry for more steps to come.
