I think China getting that information from Apple is sort of a second-order concern at this point. In a more stable situation, yeah, you don't want the police to have a reason to knock on your door. When you're gearing up to go protest in public and the cops are dropping tear gas on everybody, those sorts of lists are less important. Not saying that it doesn't matter, but there is no such thing as absolute security,…

Keep in mind that Apple's iCloud services in China are not actually provided by Apple. They are provided by Cloud Big Data Industrial Development Co., Ltd., and allows Apple to, "continue to improve iCloud services in China mainland and comply with Chinese regulations".

I used a simple mobile "burner" and was fine to authenticate. I bought bunch of $5 cards with cash in a small store and used this one in my dumb flip phone bought on a flea market few months ago. I am certain to a high degree that's pretty enough setup to stay under radar.

You can't get "burner" SIMs in Australia (where I am), I don't think. They usually require a sign up before activation; I'd be interested to know of ones that are true "burner" SIMs that are sold here.

Or join as a malicious node. There is no panacea without control over some infrastructure.

If they were doing E2E encryption, that would not be a problem. Broadcasting to find the right recipient (the one with the decrypting key) but contents protected from everybody else.
