SpaceX pauses Falcon 9 launches after upper stage anomaly
"
"In a statement about nine hours after the launch, SpaceX said the upper stage “experienced an off-nominal condition” while preparing for a final engine burn to deorbit the stage. .."
"Falcon 9 has experienced several upper-stage issues in recent years. .."

The International Space Station represents the largest single structure humans have ever assembled in space. For more than two decades, this orbital laboratory has served as a continuous home for astronauts and cosmonauts, a diplomatic bridge between global powers, and a testing ground for the technologies required to venture deeper into the solar system. However, the station operates in a harsh environment. Thermal cycling, radiation, and micrometeoroid impacts degrade its structural integrity over time. The seals are aging, the metal shows signs of fatigue, and the risk of a catastrophic failure increases with each passing year.

Except ... when this claim (not about the satellites re-entering, just the amount of damage they cause to the atmosphere) started circulating some months back, I read an article (somewhere...) that analyzed the amount and type of matter it would distribute, and it pales in comparison to the amount the earth receives in "space dust" and micrometeroids every day.
Best figure I know of for the mass of "normal" space matter hitting our planet is 5,200 tonnes / year:
https://www.scientificamerican.com/article/antarctic-study-shows-how-much-space-dust-hits-earth-every-year/
The current Starlink satellites are "gen2 mini", and are 740 kg. So you would need to de-orbit more than 7,000 of them every year - not 4 per day - to even match the natural space dust falling on earth. Except it's even worse (for the argument) than that, because 740kg is their launch mass, including all their maneuvering fuel/gasses, which by definition are gone before the satellites are deorbited. I don't have an exact figure for how much mass the fuel accounts for, but it wouldn't surprise me if it was more than 25% of the mass of the spacecraft at launch.
The residue left in the atmosphere doesn't seem to be a very big deal.
