Called it. Removing the ability for a device to connect to its own debug bridge was the obvious step after crippling sideloading.

My bingo card also includes:

• Removing the permission for the pm command to disable preinstalled applications and services at the user level.
• Preventing implicit/default permissions from being removed through adb.
• Requiring registering with Google as a developer to enable ADB at all.

We buy the hardware, so we should be allowed to use it the way we want. Fuck you, Google.

I’m sure this is completely unrelated to android’s recent decision to require all app developers to register with google, even if they aren’t distributing apps through the google play store: https://keepandroidopen.org/

Shizuku was how I was thinking of bypassing this for now, taking advantage of the local ADB connection and then using that to install apps instead of the normal package installation flow. But it looks like they want to take that away too.
