Imagine Trump is in charge of the FBI.
It is of course tied up with partisan politics, who won or lost this week from some particular story, but more transparency is good.
If the FBI had to go through the same queue as Joe Average then their requests may well end up at the head of the queue too late for action. The same goes for celebrities, advertisers and so on. All of these have different contact points. And because law enforcement contact is one step away from the company doing something that is potentially illegal their messages are given a higher priority.
You can imagine how this could be weaponised. For example FBI agents could be tasked to report tweets from people who hold disfavoured opinions. This interpretation is also inline with the court’s finding over Trump’s use of the block button: https://amp.theguardian.com/us-news/2021/apr/05/trump-twitte...
