As far as the anonymous sourcing goes, that has to do with the exposed issues that some news outlets simply claim to have “sources” and when exposed they either don’t or they aren’t credible.

Fake sources (outside the gossip and celebrity columns and a couple of cheap tabloids in any given country) is essentially a non-issue even now.
“non-credible” anonymous sources: that’s in the eye of the beholder, I guess. It is in any government’s interest to downplay the authority of any off-the-record leak source, but political parties that rail the hardest against anonymous sources generally have more to hide, and generally those stories prove substantively true in the long run.
It is still rare for any newspaper to predicate a story on a single uncorroborated anonymous source.
Bloomberg has come out with the linked story in 2021. They have never provided any other detail; no other journalist has been able to corroborate anything advanced in the story. Through grapevines, we've been able to ascertain that Bloomberg based the whole story on a single source that they massively misunderstood.
That story is the worst case scenario, and thank god, it's extremely rare to find such a blunder. Reading the comments here, you'd think half the reporting in the world is exactly as wrong as that one single thing.
