I'm deeply disappointed, this is creepy as hell.
What I really want out of Evernote is a place where I can write notes on either my Mac or my Android phone and read them on both devices. That's it. No machine learning. No human snooping. Ideally every note would be strongly encrypted with only me knowing the key, not Evernote.
I've been a paid subscriber for years and really like Evernote, but this has me re-thinking my reliance on Evernote. At the very least, it's incredibly tone-deaf as to what users really want. I've never thought, "Golly, I'd really like some algorithms, and occasionally people, to read my files." Never. But you know what I think all the freaking time? I think, "I would like more companies to respect my privacy and security above all other concerns."
