Especially combined with the discovery there are so many super Earths (rocky planets with a mass bigger than the Earth). With a larger planet, the gravity is higher and it becomes a lot harder to go to space. Not impossible, but never at the point it becomes viable for them to setup a space industry.
So it’s another Goldilocks filter. Not so much gravity you can’t get to space, but not so little going to space is easy and you end up sealing yourself in due to Kessler syndrome. It has to be just right.
I don’t know how much this filter is an issue, but it’s just one of many many filters that might all combine to produce the Fermi paradox.
The application to the Fermi Paradox is not something I had imagined before but it makes a lot of sense. Sealing ourselves in with trash.
