The FBI contacted trust and safety and said 'Hey we have concerns about these tweets'. Twitter decided to take them down in some cases.
Who is corrupted here? Twitter for taking reports and then deciding how to react to them? The FBI for finding misinformation that might lead to crazies creating mass casualty events?
The FBI at no time FORCED twitter to do anything. So it's not violating the first amendment.
All these installments have done is confirm over-and-over again that this was pretty much the normal and expected kind of interaction.
I’m not sure how institutions can say “no” to the FBI without feeling fear of retribution, nor do I want the FBI putting pressure on corporations to be something that’s “normal and expected”.
