If you are working on US based consumer web site, spying by NSA could be much more harmful than spying by China or Russia for vast majority of users. NSA is known to provide leads to police that then reconstructed evidence to exclude any links to NSA and still arrest/harass the person. There are people who are not national security risk in US jails because of NSA (mostly drug busts). BRICS countries have zero interest whether you smoke dope in your free time and won't rat you out to local police.
PS. I am not arguing that they should not be in jail. Just that NSA used semi-legal (waterboarding!=torture kind) methods to obtain initial leads.
As I said it's better to be located outside of country where majority of your users are. If your service targets american market, you can minimize risk to majority of your users by locating service outside of US. Dissident disappearing is mostly red herring - people disappear in US too (Guantanomo).
