This isn't actually about filesystem permissions. ADB is a debugging tool that seems to have been used by certain applications. It shouldn't be required for any normal app functionality including storage access. That said this is still a user hostile change. I will never purchase a device that blocks ADB since it's required for several useful things, often related to fixing or working around issues created by the vendors themselves.
