I would love for more things like this. We do have this for phones at least with their teardowns. However appliances aren't so "hot". Might be more difficult to make a business out of it, particularly because "information wants to be free". That makes being a primary producer of information risky, and if it's not something that brings frequent eyeballs on it, then it might not go so well. As Appliances are something we only want to deal with no more often than once a year, the eyeballs won't come, and you have to deal with people absconding with your information and making it free.

Edit: and yes, this is the same issue that journalists face. This wouldn't be much different from journalism. The function of journalism is supposed to be the independent watchers, for example, in government so that we can keep them honest. Same sort of deal.
