I think few who enabled Sentry Mode thought it was reasonably likely that Tesla employees would share titillating personal moments spotted by their cars for the luls.
Video footage being shared with/accessible by Tesla should be strictly opt-in - especially for "sentry mode", which is the most likely to catch someone in their skivvies (or worse) in their garage.
I'm not saying that it is right. There's a real lack of transparency here, especially considering how many people seem blissfully unaware.
