> If the shutter fails to open to spec, would you want them to know about it and have data to improve it via a firmware update or next version of the product?
You are not being forced to reveal anything :). That is coming from your standing POV that this data is yours.
Look at it from the perspective the data is not anyone's to start. The data is something you played a role in creating but you do not own. Next, how do you decide who controls and gets access to which parts of the data and what are the reasons behind that?
Data that identifies you might own and keep private.
Data that can help the manufacturer improve the product/services they might get.
You are arguing that I should be, though. Whether or not I "own" the data is irrelevant to this point. If I don't have a choice about it being revealed, then I am being forced to reveal it.
> Data that identifies you might own and keep private.
Given that very powerful databases and data mining technologies are commonly employed, I think that this category covers the vast majority of all data that is created as a result of my actions or the actions of machines that I own.
Not without my explicit consent.
