Yes, actually it was. Go actually read the lawsuit. It sought to ban federal agencies across the board, including CISA, from communicating at all with social platforms.

Gateway Pundit was one of the plaintiffs and he sued because Twitter banned him for repeated election disinfo (e.g. stolen elections) and he was mad that CISA contradicted him. So was Trump who fired Chris Krebs for having the audacity to say the election wasn't stolen.

The entire lawsuit was just a part of a right-wing grievance campaign against the idea of social platforms, NGOs, or federal agencies doing any work to moderate social platforms.

The world is stupider for that campaign largely suceeding and come the next pandemic, thousands or millions could die thanks to platforms being afraid to do even the most basic moderation.
