Windows used to always give a little popup saying it was installing drivers when you plugged shit into it. Now, apparently, TVs are for some reason trojan horsing this.

There's no reason to expect a normal user to think "Yes, this port is the USB port and thus commonly needs driver updates, but that HDMI port does not ever need driver updates." Most people don't even know it's called a USB port, let alone whether it should host driver updates. Besides, I could imagine a scenario where there's some outdated HDMI decoding thing on it. Or maybe just some tech for home theater stuff I'm not aware of.
