> Patch iOS and Android applications, embedding a Frida gadget that can be used with objection or just Frida itself.

This is the key thing, and the part that will change next year: previously, you could unpack, patch, and repack an APK with the Frida gadget and install it onto an Android device in Developer mode, while the device remained in a "Production" state (with only Developer mode enabled, and no root). Now, the device would either need to be removed from the Android Certified state (unlocked/rooted) or you would need to sign the application with your own Developer Console account and install it on your own device, like the way iOS has worked for years.

Wow that's horrifying. I guess apk modding era is over for most users.

Not yet. If I recall correctly only very few countries affected in the beginning.
