I plan on just blocking it in my router, but who knows if the TV scans around for open hotspots. If I were a "smart" developer Id store everything locally if offline, then dump to the manufacturer if it ever does get a connection. Not my problem if the feds happen to be "selecting" for that dump somewhere upstream...really not my problem if they have a dragnet FISA warrant for the data.
Where is that noble hacker who'll make a tutorials on how to destroy smart TV WiFI radios?!
