I like this point. I have never thought that sometimes "less is more" even on information.
Blockchain giving traceability and transparency is a possibility for people to get to know more the product/service they are buying. If they are interested, they are going to look at it. Otherwise, they can be waiting for more curious people to yell at scam if the Blockchain shows sth not aligned.
So, beyond flooding people with info, it's also an external application of the "Theory of the Games".
