Adb is just an interface between computer and phone, the packages it lists may not be every system component, you can add anything in at kernel level, or also just not list it in that interface.

Not if they’re baked into the system. Although that may get into GPL violations, I forget. God knows a device can come with locked firmware though.

You know, if everyone pirated everything for long enough, there’d be no more money for all these content resellers to lobby Congress with, and copyright would just die.

American discourse is a neverending pit of bullshit. People will defend a lie to their deaths.
