I think calling them dangerous is even a bit misleading as they're well tracked. Some of them even autonomously precisely position themselves rather than be on ballistic trajectory.
Only the largest objects are trackable. Objects in the 1-10 cm range are large enough to destroy satellites instantly but too small to track. Obviously any visualization will only show known objects.
This explains both why "dangerous" is accurate, and why autonomous avoidance based on tracked objects (ala Starlink) is 'necessary but not sufficient.'
