How to defeat this
Unless television manufacturers make very clear up front there is advertising embedded into the device in the display in the shop, in the marketing material then people should just return this crap and complain to trading standards. And by very clear I mean the demo model in the shop should show this advertising and any pictures of the functionality should also show this advertising and any feature list / specification should state there is advertising and the form it takes. And also any other personal data or metrics gathering that the device performs.
Perhaps if retailers get enough returns they might even get fed up of being the conduit for this shit and tell the manufacturers to knock it off.
