I see a lot of HN users living in HN bubble completely forgetting that we are a minority of consumers. Most of Reddit audience is either not educated enough, don't have enough exposure to see the difference or simply don't care. Did we all forgot about eternal September already? So, unfortunately, no - users won't even notice this because they have no idea what's valuable to them and they will buy anything as long as it's packaged nicely. For the same reason they also won't vote with their wallets even when (as you say) "everyone" knows that testimonials are garbage.
