Go through the list of countries / actors Twitter has previously disclosures on, Russia, China, Venezuela, Iran, Spain (Catalan separatist), I think Bangladesh at some point, and these disclosures are functionally US propaganda.
I don't think Twitter is an intentional state actor, but who they report on is constrained by limited resources which means they're incentivized to report on (and censor) US geopolitical rivals even though every serious intelligence agency will run information campaigns.

Lawful or not, I don't think Twitter has the balls to expose information campaigns contrary to US interest, which is going to be a recipe for more internet balkanization.
