China’s constellations are going to orbits that will take hundreds of years to return to earth and could make launching much harder if there is a collision. As far as I know only SpaceX has satellites in low orbits that frequently need propulsion to push back up, and fall back within 5 years.
Fun fact: SpaceX has packed some segments of LEO so densely they surpassed the local Kessler syndrome density. In other words, even if the debris deorbits by itself in LEO, you can still cram enough sats in an orbit that just a single impact leads to follow on impacts fast enough to get a runaway chain reaction.
OK and we aren't going to stop China from doing it. They do what they want. So there's nothing to fuss about.
This article mentions SpaceX 7 times and China once incidentally, they want to nag SpaceX into doing things that don't matter when China's launches do matter and nobody is going to nag them into decelerating.
