Apple should add a status bar icon that appears whenever your camera is on and in use. Or even color the status bar similarly to how they do for GPS, tethering and calls being active.
At my newish job I don’t communicate with anyone overseas but I can see why people would need to use WhatsApp.
Next up, Google Maps and Gmail. I plan to use Fastmail but I need a domain without my name in it for non-professional use.
However, WhatsApp is the killer app that I’m being peer pressured into keeping on the phone because of social effect. There is just no alternative to it in sight :-( I wish.
Gmail -> FastMail. I’d heartily recommend as a very happy customer.
Google maps is still another cancer I don’t know how to get rid of.
If FastMail could keep my data away from Google and other advertisement companies, I’m all good. Although I wish Australia doesn’t do something as stupid as this law.
Signal is great for when you want to talk about things that governments have decided shouldn't be talked about.
Obviously that might not be enough for everyone, but it's by far the best solution that works with existing hardware. Tomorrows phones might have indicator LEDs or hardware switches, but my current one doesn't.

Hell, even integrating it into the phone and opening the camera app when i open the rear slider would be a killer feature.
