> a single quote from a single astronomer whose only warning is...
It's not a quote, but the article also has Allen saying that "it could cost between US$10,000 and US$100,000 for each telescope to correct the problem, and that corrections will be tricky to implement."
It also has another astronomer claiming problems: "But separating time from rotation would mean that telescopes would no longer function properly, according to Patrick Wallace, an astronomer at the Rutherford Appleton Laboratory in Oxford, UK. Most telescopes with a viewfinder wouldn't be immediately affected, but instruments that track satellites and other moving objects could feel the effects within a few years, Wallace warns."
It sounds like FB/Meta is correct in saying that Astronomers did object. I'd suggest (like Mata does) those objections are not especially important considering the trade-offs though.
