> Revealed preference only makes sense in a world of perfect information.
No??? Revealed preference is dependent on what information is known. The analysis is made easier if the information is perfect, but that is not at all a prerequisite to being able to lean on revealed preference.
> In fact, the revealed preferences is for TVs that appear not to spy on you, that's why they hide that information!
Exactly! Consider though that, as the information landscape changes, so does the revealed preference. Notably, when things like TVs spying on their buyers comes to light, a preference can be revealed that buyers don't want TVs that spy on them.
Like, it's entirely rational for LG to want to hide this fact about their televisions, provided that they have the inkling that this would be unpopular. Their behavior in trying to suppress this press leads me to believe that they know exactly how unpopular this is, and they're trying to get away with it anyway.
