Already since recent iOS versions have started popping up an alert to grant access to local network resources per app, I&amp;#x27;ve noticed this popping up on several apps that have no business mapping and fingerprinting my LAN.

I doubt &amp;quot;I want to submit a pull request to iSH&amp;quot; would be considered a valid reason (but correct me if I&amp;#x27;m wrong).&lt;p&gt;Even things like camera access in multitasking views are entitlements that your dev account needs to be preapproved for. In fact, it wasn&amp;#x27;t even something that Apple even publicly mentioned for a while - only Zoom had it until someone reverse-engineered their app bundle and found out about it.</text></comment>

Surely they must know what is going on in every app, that&amp;#x27;s why the App Store is so safe.</text></comment>
