I liked the article. If you are gonna update it, please consider also mentioning technical aspect. Frankly, Amazon snooping on users is to be expected, but short mention of app for which platform have you analysed using which tools would be welcome addition.

Snooping on users during e-commerce transactions, sure.

But recording user's detailed interactions with every ebook? I hope that's a big surprise to your average Kindle user.

It would be great to see a data request response and how much of this data is retained and for how long. It's clearly not anonymized at the request level.

Very easy to see a future where just reading certain books or reading certain books too many times could flag you as dangerous or be used to support a mental incompetence hearing resulting in loss of rights.

I doubt it. Here are some features the Kindle phone app intentionally advertises to the user:

- prediction of how long the book will take to complete, based on your reading rate

- tracking of whether or not you read anything on any given day
