My parents got a new smart TV; if you don't give it wifi access it will nag repeatedly about it. Very annoying, and it only takes one time for it to go "Yay! I'll store these forever now."

(It will also wheedle you to re-enable the AI features and telemetry if you turn those off. Which you do like eight levels of confusingly and scarily named submenus.)

Tell your parents that with this stuff enabled, it's giving another way for scammers to steal their data to use against them.

I.e. We're from the internet company. Really, you are? Yes, didn't you watch XYZ on Netflix last night? Oh, right, ok, here's my password.

The best course of action here seems to return the TV. Any TV that cannot be permanently switched to HDMI input without nags is unfit for purpose and should be rejected.
