Car GPS devices have had them built in for almost two decades now, and they routinely sold for around $100 or less as a one-time purchase once they were relatively common (unless you wanted weekly over-the-air map updates rather than monthly or quarterly). Far more TVs are sold than those car navigation units ever did. I don't think money is an issue if they want a slow back channel. If they wanted to ship all ads over it, sure, but periodic phone-homes? Updates to DNS-bypassing lists of IP addresses? Unless they're prevented from selling it, they'll do it eventually.
