I don't think they are deliberately undermining anyone. The Australian government introduced a policy to prop up a specific powerful media organization that is loosing readers and money. Facebook for all their faults are not the bad guys here. They have to abide by the law of Australia, they had a short period of time to make changes to remain legal, they have likely done the minimal amount of work to abide by the new Australian law. It's likely far easier to flag stuff as news than not news with the amount of edgecases. What we see here is a consequence and collateral damage of Australian government policy put in place to keep rich donors rich. It's likely over the coming weeks things caught by the sweeping ban will slowly start getting allowed back as tweaks are made. If you need to be mad at anyone, it's the government who introduced a policy resulting in a company saying, na, it's not worth it financially we'll move out of that market.
