None of these concerns apply to Starlink. The satellites orbit low enough to quickly decay if they lose power. They deploy even lower than operational altitude so any associated junk comes down even faster, and the deployment method of just spinning and unlatching the stack, combined with SpaceX's philosophy of using repeatable systems (eg mechanical separators instead of explosive bolts) means that Starlink launches produce minimal debris and any debris produced is short lived.
The issue with the Dish satellite is that it's close to geostationary orbit, which is a limited resource and where the atmospheric drag is low enough that they are essentially up there forever.
I'm probably the only person on HN confused by this comment, but I assume you mean Starlink, not Starling, which is a NASA mission involving 4 cube sats.
