What's yours stays yours... except for when we stuff up the login system and let anyone login to your account? Yes I know it was a mistake, but now that you've sorted out the licensing terms, lets move onto the issue of showing people you have improved your security model. Many people put pretty important stuff in their Dropbox, prove them that it will be secure. You need to come out with a blog post outlining all the new security incentives you are doing to win peoples trust back in that regard. Perhaps look at offering two factor authentication like Gmail (I believe they open sourced that), or at least when you setup a new PC to sync you need email confirmation like Steam. Maybe give people the option of having 'extra secure' dropbox folders that require you to give an extra password to access.
