For those of you still having issues with this, and are using a Roku TV and do not want your content to be watched or served ads, you can just change the TV's wifi network to a mobile hotspot, delete the old network, then disconnect your mobile hotspot. Yes, you lose the 'smart' features, but considering many of them reset on their own to re-enable things you've disabled when the TVs update, this is a much better solution for our privacy.
Don't trust them.
