I was mostly taken by the author's stance that "storing" a customer's data is somehow unacceptable. This quote was the big one: "[Quoting Fastmail:] We also store information from your address book, calendar, notes and files on our servers. [The author writes:] Is there anything you guys don't store?" Is not the purpose of an e-mail provider to...store e-mail? On their servers? For me to access? I am very confused, and I genuinely mean that. Most of the author's complaints come from storing the data that I have paid them to store and then taking actions on that data in response to what I have asked them to do.
