It sure doesn't seem like a mistake. Twitter itself used to make the distinction between state-funded (without editorial control) and state-affiliated (where the state has editorial control) on their own Help Center [1].
They removed the distinction on 2023-04-07 [2], two days after they slapped the state-affiliated label on NPR. That timeline sure doesn't sound like Musk made a mistake and sought to correct it, but more like he swung his whiny authority around and then people had to scramble to retract/alter policies to fit with Musk's world view.
If it was a mistake, Twitter would have owned up to it instead of altering their policies to match the mistake.
