Agreed. But I think the right to monitor the police doesn't have to mean real-time access to police radio. The radio could be recorded, like body cam footage, and released on demand with FOIA. FOIA allows redactions when needed, so sensitive information like victims names and addresses could be redacted.
This is worse. Let's go with an example: on an Android phone, you visit a website. The website asks for an integrity check, the browser works with Google Play Services to complete the check.
What if you have a de-Googled phone without Play Services, or if you made modifications to restrict Google's tracking? Then Google can refuse to verify you. What if you installed an ad blocker in your browser? Google can refuse to verify you.
If you fail verification, the website could ask you to complete a captcha, or just refuse to show you anything.
You can make an app with Tauri without writing a single line of Rust though. Tauri lets you trigger most native functionality you might need from the JavaScript side. If that's enough for what you are building then you don't need to write any Rust. You could use a Rust web framework that compiles to WebAssembly, but you could also just use React or Svelte or whatever else.
You couldn't make a proprietary server. Client is fine, AGPL doesn't apply when you are accessing the server over a public API.
