Quotes to what Musk said:

""Musk wrote on Twitter today (May 27) that he's already instructed teams to look into making future Starlink internet communications satellites less shiny to lower their "albedo," or reflectivity. He pointed that out in response to a direct call from a com menter on Twitter. ""

"Exactly, potentially helping billions of economically disadvantaged people is the greater good," Musk wrote in response to a comment on the service Starlink's constellation would provide. "That said, we'll make sure Starlink has no material effect on discoveries in astronomy. We care a great deal about science."

“I am confident that we will not cause any effect whatsoever in astronomical discoveries,” Musk said. “Zero. That’s my prediction. We’ll take corrective action if it’s above zero.”

Musk went on to add that SpaceX was “running a bunch of experiments to paint the phased array antenna black instead of white,” a possible reference to the so-called “darkened satellite” launched by the company earlier this year.

He also noted the company was working on a “sunshade” for the satellites, adding: “There are certain angles where you can get a reflection.

“We’re launching a sunshade, changing the color of the satellite… aesthetically this should not be an impact.”

From 2019.

Proves my point, that

A. The article is misinformation.

B. Musk said they'll make sure to not mess with astronomy, doing a variety of measures on the sats. He never claimed that such effects as light pollution wouldn't happen in the first place.
