The social network company recently announced it's banning all Australian news content from its platform amid a row with the government, but British MP Julian Knight - who chairs the Commons media select committee - has accused the company of acting like a bully.
He told the BBC: "This is a crass move.
"I don't think they are being a good citizen, not just in Australia, but elsewhere [too].
"To pull the plug overnight represents the worst type of corporate culture."
Steve Evans, a reporter for the Canberra Times newspaper. has also slammed the tech giant for its handling of the issue.
He said: "They botched it, there's absolutely no doubt about that.
"Not only did they block media organizations, but they blocked government health websites. So access to up-to-the minute information about COVID, for example, was suddenly not available on Facebook."
The social network site recently issued a statement explaining its decision to ban all Australian news content from its platform.
William Easton - the Managing Director of Facebook Australia and New Zealand - wrote: "The proposed law fundamentally misunderstands the relationship between our platform and publishers who use it to share news content.
"It has left us facing a stark choice: attempt to comply with a law that ignores the realities of this relationship, or stop allowing news content on our services in Australia.
"With a heavy heart, we are choosing the latter."
