Dropbox is generally known for reliability in the face of competitors, however issues like this one and the highly embarrassing "anyone can login to anyone else's account" bug of 2011 definitely cast some doubt on using it as a sole storage option, or a solution to store any sensitive data. Most medium-sized and large companies refuse to touch Dropbox due to these reasons, especially in the financial and medical space. That said, I still employ it for personal use and like the product in general.
