I was about ready to move all my email over to Fastmail before this happened. But not now.
Though that’s not to say that we should accept these laws as they apply to email services lying down. Any reason to refuse to use the services of Australian companies when foreign services of similar quality exist gives those Australian companies all the more reason to press the government to reform these laws on the grounds that they’re losing valuable business for negligible gain to national interest. If the government doesn’t listen to individual constituents, it might listen to companies which are hurting in their back pockets.
