Don’t take the headline as truth. Consider the source when interpreting the information.
It seems entirely reasonable to me for government officials in the context of meeting with Twitter to talk about what could be done to slow the spread of disinformation, to say “Hey Twitter, you say your policy is to ban spreaders of vaccine disinformation. This person is clearly the source of a lot of it. You’ve banned many others, but why not him?”
Encouraging Twitter to enforce its rules consistently is a totally reasonable thing for the government to do, particularly regarding public safety issues.
