As more companies look to offer space-based services, space junk is likely to pile up. Fines will ensure that the industry works to clear the mess it is making too.
US imposes $150,000 fine on Dish Network for space debris::undefined
Adding onto what the other commenter said, LEO satellites (the orbit Starlink uses) just don’t have the same operational lifespan as geostationary satellite (the orbit of this Dish Network satellite). They experience a ton more drag because they sit under 1k km, while geostationary are up at 36k km and as such LEO satellites require way more fuel to stay in orbit.
This is not to say 4 years is not on the lower end of LEO satellites which are usually expected to last 7 years, but geostationary satellites are over double the expected life span at 15-20 years. Finally, even though Starlink is more wasteful, their satellites will fall out of orbit pretty damn fast (within a couple years) compared to geostationary satellites (30+ years).
