To each their own, but I am far more interested in what happened, what they are doing about it, whether it can happen again, and why I heard aboutnit on HN instead of directly from Dropbox.
I personally am not interested in an apology or a gaveling tone. These people are not my personal friends, I don't have an emotional investment in whether they pretend to care about my feelings. I have an objective intrest in how they choose to act and the information they give me so that I can make my own informed choices.
That makes it sound like it was primarily the fault of the developer who created the bug - things like this indicate an inadequate process or culture not simply a mistake at the developer level.
Edit: Does Dropbox have any testers or is all testing based on automated tests created by the development team?
Or decide how to balance the risk-benefit equation. Perhaps this will inform my choices of which things to keep in my dropbox and which to keep elsewhere. For example, I might decide that my secrets are fine there, but it is inappropriate to store client secrets in Dropbox since the client has certain expectations around my respect for their privacy.
