This is exactly what I've been thinking about the whole satellite internet constellations that are getting launched. If governments required interoperability and open access to any network of...say 10 or more satellites we wouldn't have 3 or 4 or 5 incompatible swarms of thousands of satellites crowding low earth orbit and threatening kessler syndrome. We could setup one global satellite internet solution and have competition on the ground for who your connection goes through while it all operates on shared infrastructure.
And instead of taking an approach to actually help fix the problem the EU is just making it worse by encouraging yet another incompatible constellation of hundreds or thousands of satellites to make LEO even more crowded?!
