Never heard of 'em. Could be my fault, I suppose.including Evernote, Jawbone, and Tango
They're noteworthy inclusions because, like Dropbox, they've been around and actually should be making a profit. Evernote makes organizer software on a freemium model and are the one name anybody knows in the space. Jawbone makes bluetooth equipment; in addition to having probably the best noise-cancellation algorithms on the market they also make the designer douchetags that iPhone users tend to favor. With you on Tango; they appear to be Skype, except largely owned by Alibaba rather than Microsoft. Which muddies the analogy somewhat but also indicates the larger point of the article, which is basically "the money is sick of your shit."
I recall unsubscribing from an email from Evernote. Still have no idea what it is though.
