I can't find any such app.

Apple falling will be insufficient, as another overlord will take over. Host your own is probably the only answer.

I'm not saying it is the case, but considering other tactics employed by ICE, this sounds like something they could deploy as a honeypot to profile potential targets.

They could and they could even make it a PWA so it would be on the home screen and able to send notifications.

But they only want to support native iOS for whatever reason (they've listed their reasons: https://www.iceblock.app/android, I just don't personally believe them to be technically accurate/truthful).

It is a webpage, they just had an app to view it.

"law enforcement" is charitable.

As gets pointed out, that justification is post hoc; the argument wasn't made when the app was introduced, only after the ban. It's also leaning hard on "can be" and just letting the reader infer what "malicious" means. Clearly the intent is that protestors can show up to disrupt enforcement actions. Is that what you mean? If so, you should say so.

But it's also just plain overbroad: the same logic applies to Waze flagging of speed traps, which are also "crowd sourced law enforcement location data".

Basically this is bunk. The app got banned because the government doesn't want its enforcement actions disrupted by protestors, and whined[1] to Apple to coerce them into a ban.

[1] Plausibly threatened. It's not alleged here but they did it to Disney and Paramount already.

Are we allowed to post the location of roadside cops on google maps? What exception to the first amendment allows the government to abridge such speech?

That same justification can be applied to block web browsers, any social media platform, and any navigation app that allows user alert inputs.

The entire thing reeks of the same Biden-era pressures on companies that had pandemic misinformation that Republicans were so vehemently opposed to. Somehow harming law enforcement is a better justification than harming random citizens.
