It's because of the precedent effect. Countries very much look to each other for policy guidance because nothing is better than having facts on the ground in deciding whether a policy works or not. We've seen it especially recently with COVID-19 responses. Facebook/Google need to make sure that policies like this aren't enacted because whilst Australia is tiny, the US and the EU aren't and will adopt a similar policy if it works. And then suddenly it snowballs into something you can't stop.
