Even as a non-typical dropbox user (a developer, then), I think there should have been some kind of a warning a, some ability to recover from the situation b (I was left for nearly a month with a completely non-functional dropbox), and not suddenly getting dropped without warning by support c.
If I'd known up front that a deployment of not that unusual amounts of code (especially if you use git) would have led dropbox to irrecoverably fail for me, I wouldn't have used them in the first instance.
I don't think even as a 'non-typical' user the very poor, typically big co, experience I had was justified, esp. given that I am a member of the group of people who first started using dropbox.
