There were a few TV models a couple of years ago that would stop working after enough time without a network connection. When they reconnect, they're clearly going to download a new cache of ads and transmit their existing tracking data.
It's easy to assume that they'll eventually require an unabridged connection to their own servers for updates, and they will simply send all ad data through the same routes such that you can't block one without blocking the other.
This is too lucrative for manufacturers to pass up. The added complexity also ads more points of failure and drives faster industry-wide consumer upgrade cycles. This is not something that will be fixed in the market alone.
