Mailbox was an acquisition. Carousel was launched by Dropbox, but it came out of their acquisition of Snapjoy.

The problem wasn't simply that they shuttered the services (particularly Mailbox), it was how they did it. Mailbox spent about a year with development completely stagnated. Essential features like searching were broken and Dropbox's response was "we're refactoring! Don't worry, big updates coming soon, please be patient!" And that went on right up until they said "Okay bye!"

Services get shut down. It sucks, but it happens. But stringing your customers along for a year knowing perfectly well that your product is not being worked on is pretty awful.
