Protect your company information!
Any multi-million company will have (I hope) a policy on protecting their confidential company data. That could be financial information, product schematics or secret recipes. That may include not using cloud storage for their most sensitive data in case of loss/leaks.
I see a direct comparison here. For these celebs their image is the product. They hire management to ensure they're seen in all the right places, and don't get seen in the wrong ones etc. These managers should be making sure the product isn't at risk, and that should include digitally - making sure sensitive *ahem* data isn't in the cloud or just about anywhere easy to steal/lose.
All in all, I put it down as a management cockup.
Cockups? leaking? Well there can be only 1 icon now...
