Frankly I want Australia to go ahead with this law so the rest of us can have a test case for it. If it works well we can copy it with tweaks. If not, then we know to seek other options.
What is the acceptance criteria for this test case?
Government dissent is successfully abolished from social media (the real reason for wanting to abolish anonymity via gov't ID requirements)
Bold claims need proof. Does Australia have a history of that?
During COVID times the Australian government pressured all local media to censor criticism of the government's COVID measures. Regardless of how valid or invalid you consider the dissent, it was still dissent being suppressed.
