I recently bought a Samsung Smart TV (they simply offer good value for such a little price). Best thing to do is to never even start connecting it to a WiFi network and use an external TV receiver. That way it most certainly will not connect to any network whatsoever. I also never agreed to any terms that are on the start display, which may also add to that. Just switch to your Input channel (external device etc..) and enjoy your "dumb" TV.
