TVs and other gadgets that have no microphones or video cameras embedded in them should have a certification like "organic". "NoSpy Certified" or a similar trademark would be appropriate right next to the UL and CE marks.
You know that every loudspeaker can be used as a microphone, do you?
You know that even stuff without radio can be converted to send files wireless (e.g. CPU as radio, already published a while ago by someone)?

UL may be a 'joke', but it does keep a lot of sketchy electronics out of the market (at least in the US). In my personal experience dealing with them, bad hardware design is more to blame for a bad experience with UL than the UL process itself (which, is brutally long, but just might be for a reason..)
