Sounds like they might have the capability to just network block the device from their router too. At least that’s what I do, just in case someone tries to use it.

There are plenty of uses for it. There are also plenty of bad implementations that don’t use it in a way that helps anyone.

We’re going through an overhyped period currently but we’ll see actual uses in a few years once the dust settles. About 10 years ago, a similar thing happened with AI vision and now everyone has filters they can use on cameras and face detection. We’ll reach another plateau until the next tech hype comes about.
