content: The scary part is that anything related to the cloud (including dropbox) wants to be your private data, and be your company data, and share anything with strangers like some social media. The borderline between private, company and shared data is razor thin like a bit in the database. One small bit change, by a corrupt database entry and all your private and company data gets shared with the rest of the world. One idiot developer that forgot a "!" sign could expose your nude pictures to the company colleagues and your boss. I also agree with you, there is no guarantee that Microsoft and Adobe can keep the operating costs under control and do not go belly up. Or worse, your company files being altered or wiped out because it is targeted by DMCA take down.
