I think every ISP or storage provider has something in place. Just the allegation that they were not doing active measures to stop child porn can put a medium sized company out of business.
As for risks, I recommend people prioritize. Compared to the Chinese and Russian malware outfits churning out the latest successor to CryptoLocker this second, worrying about the NSA or Google is way down on the list.
Worried about the ISP? VPN software and servers are available. Worried about physical security? Windows 8 and Windows 8.1 support BitLocker in their Professional editions. Worried about attacks through your Web browser (which is, as I recall, the primary source of infection?) Use Chrome or Firefox and either a sandboxing program (Sandboxie comes to mind) or a virtual machine to run the Web browser under. I personally use both so malware has to get out of the sandbox, then out of a VM before it can do damage.
