Should An Official ABC Twitter Account Be Saying This?

What exactly is an official ABC Twitter account doing tweeting something like this?

Now, whether or not the opinion expressed is valid – (and I’m making no particular judgement on the opinion expressed) – whoever is operating this account on behalf of the ABC, should be expressing this opinion on a personal account, not an ABC branded account, given one of the guiding principles of the ABC Charter is impartiality.

When challenged by another tweeter, the operator of the account went on to defend the original tweet:

Poor.

Very poor.
