The really stupid thing about the FBI pay story is that US law requires US law enforcement to pay for any costs associated with processing legal requests, in part to put law enforcement off fishing expeditions, but mainly to ensure that companies are not out of pocket for complying with law enforcement orders.
So if the FBI presented a court order to Twitter, or Facebook, or Truth Social requiring information about a user the FBI from memory had to pay the costs associated with getting that information (I can't remember if there is a statutory amount).
It's basically the same as if the FBI required a wiretap on someone's phone, they had to pay the telecoms company it's going rate for the time it too to connect that wiretap.
