I didn't say they do, but they should hire people competent to make educated decisions in the regulatory environment they're in. That's why they pay bofhs -- not because they like our views, but because we _read_ the specs.
EDIT: To phrase less hostilely -- HIPAA and various finance laws consist of thousands of pages of what to do and what not to do. Dropbox is a shiney webpage that isn't PCI certified or HIPAA certified. If you chose to operate in a business that requires HIPAA/PCI, and used dropbox for that data, _you_ are at fault, not dropbox, not the bofhs, and not the coder. In the case of HIPAA - you would be the criminal.
