That's not true. The us government is asking for the account holders identities (no shut down request) because the government suspects that the account owners are civilians (or possibly foreign actors) posing as federal employees. The account derives it's authority by saying that it is run by employees of a federal agency. It's a serious federal crime to impersonate a federal employee. The government has not asked to shut down the account.
I suspect the government will make a decision after they know the identities, but there is just enough evidence to assume the account holder is faking their authority as there is to believe its real.
