There are regulations around de-orbiting your spacecraft at end-of-life, and there are international agreements around weapons in space that refer to the generation of debris.
I don't understand how a lack of regulation would mean something isn't a big problem. It could for sure use much more regulation, as it is such a large problem.
Seems similar to the angst when SpaceX launched the first constellation of satellites and astrologers cried that their images would be ruined because the sats are visible on long exposure shots. There was some initial backlash, then total silence. Perhaps because there are no follow-up articles, so the whole debacle seems like theatre to the layman.
