This is actually not correct for Starlink. They did a lot of work to lower their albedo based on astronomer complaints, even though there wasn't any government regulation in this area.
It might apply to some of the emerging Starlink competitors however, especially the Chinese ones and AST.
The albedo reduction they worked on is the exact reason why I wrote this, "...or if they think that a government order is imminent so they come to some voluntary agreement ahead of time."
SpaceX only "voluntarily" did that because the government was likely to put more stringent requirements on them if they ignored the complaints.
