I mean, Twitter has (successfully) refused subpoenas for things like demasking pseudonymous users in the past. Of the big social media companies, (pre-Musk) Twitter has probably historically been the most pro-user in refusing to bow to legal pressure.

Good point, they went to bat for their users on multiple occasions.
I have huge respect for the former legal department of Twitter, being under pressure from so many sides including many state level actors must have been extremely difficult. And to see it all squandered like this must be extremely painful.
