I let my TV on wifi, but block internet access at the router. Things like Airplay and Chromecast still work great, but no ads/tracking/etc.

Is that tied to the port or the MAC because the device can just change addresses and you won't know.

You would know if your device starts updating. And if it changes mac to get around the block then it goes in the trash.

OpenWrt, make a wifi network only for those nasty spying devices, printers, tvs etc

Same!!! I do every so often connect it to update it if a newer firmware is actually worth it… The extra upside to not accepting the terms is that none of the samsung bloatware apps even start - the TV runs much faster than just with the wifi disconnected.

It doesnt matter if you do or dont, those things are worthless in court in any reasonable country. They frequently want their users to agree to illegal things.
