While I'm sure there are some messaging aspects to doing it early, it's worth pointing out that by January, unless the government repeals the law, Meta will be penalized for allowing links during emergencies. This specific law comes into operation regardless of whether the government has published any framework or not.

This is a power play protest about avoiding being subject to other countries’ law.

Meta is complying with this law. The idea behind the law was that Meta was stealing ad revenue from news organizations by linking to them, and that if they wanted to continue linking to them they needed to compensate news organizations. Meta has thus stopped 'stealing' the ad revenue. That's complying with the law. It did exactly what it was expected to do, in the same way that when you tax cigarettes you expect some people to cut back on smoking. Even better, Meta stopped 'stealing' before the law even came into force!

Seriously it's like there's nothing they can do to satisfy their critics - they get accused of stealing news so they stop it, and then they get accused of harming news sites by not stealing.

Which is it? Is Meta beneficial to news organizations or harmful to them? If harmful then there's no problem with Meta blocking news links. If beneficial, then maybe this is a dumb law that's akin to the government putting a tax on exercising.
