I agree that “random server” is a bad choice of words, but do want to add additional information context as the concern isn’t necessarily unwarranted. Another qoute from the article:

“I have determined the business need is higher than the security risk associated with this implementation and I accept all risks,” wrote Aram Moghaddassi, who worked at two of Mr. Musk’s companies, X and Neuralink, before becoming Social Security’s chief information officer, in a July 15 memo.

Its also sounds like they did spin up a new database with limited security/oversight to “move” faster. Why that’s worrisome is they aren’t denying there is a risk or lack of security, they are just saying it’s justified.
