And importantly, if the individuals using the platform are (hypothetically) being silenced by government agencies levelling threats against the company unless it complies, this could be seen as tantamount to censorship.
Twitter doesn't have that. The employee handling the request doesn't own Twitter. If something happens to Twitter it doesn't happen to them except in a very abstract way (and the person who did fire them was Elon Musk in the end).
Governments absolutely have a means to intimidate contact owners: it's subpoenaing them to testify before Congress. Not emailing a mid-level content moderation supervisor who has no way to directly talk to the board of executives or shareholders.
At the corporate level its also threatening because of the actions the govt could take against the corporation. Look at all Musks companies now undergoing heavy auditing since he messed with the FBIs twitter.
You have to be naive and only see the happy path and think the govt always has your best interests in mind to think otherwise.
Can you point to examples of this? I hope you’re not referring to things like the earlier investigation of Tesla’s FSD claims when that’s been underway for years and so widely predicted.
Corporations are not people: you can't "tell" a corporation to do something, because the people who make it up are a mercurial, constantly varying group. Even if the owners know something, the employees don't: training materials have to be updated, policies modified etc. You can't "imply" a threat to a corporation, because how do you "imply" the threat to all the people who have to actually implement the desired action? How do you replace staff who are not in on "the implication"? You can't: somewhere and somehow you would have to have internal emails, training and onboarding materials.
If the FBI contacts "Twitter" then they're not talking to any one individual, in fact there's no requirement that be the same person at all.
So Twitter cannot be threatened or threatened with implied threats - it's a limited liability corporation, there's no individual who can be overly inconvenienced or have any emotional reaction to the request.
