It's naive and dangerous to think that the NSA's actions are unique. Nearly every developed nation on the planet has a similar intelligence arm which isn't as forthcoming about its procedures for requesting and gaining access to service provider (and ultimately corporate) data. As stated in the ITIF report, German intelligence has the G10 act which let's them monitor telecommunications traffic without a court order.
The fact of the matter is that the IT services market is a part of our portfolios because it provides capabilities we value either against IT or business metrics. And it's highly likely these values are worth more to you than the potential risk you think your company faces due to government surveillance. And if your company is a prime target for government surveillance, you are probably being watched from within your own firewalls right now.
... you can take actions yourself to protect your data from prying eyes when using these services. A quick tip: bring your own encryption. If you hold the keys the governments can't get to your data by going through your service provider.
