As I see things, the only possible way that the NSA's misuse of their powers (specifically regarding non-US persons) is likely to get curbed is when companies realise there's significant revenue implications. I have _zero_ voice in US intelligence gathering policy. I _do_ though, have the ear of people buying services from US companies who _do_ have a voice in forming/changing those policies. Google's position at the top of the web search food chain, and the amazing advertising business they've built on top of it, might not be enough to justify the risks involved in exposing all that data to the NSA. Microsoft/Yahoo/Google's enourmous slice of the webmail market is also a dubious value proposition if you evaluate the risks in a certain light. Amazon's dominance of the "cloud" market isn't unassailable if you take legal jurisdiction and corporate ownership into account. Salesforce becomes suspect as well for non-US users (both as a CRM and their entire force.com platform).
Those are my most likely allies in lobbying for non-US-citizen's basic human rights online. If Google, Microsoft, Apple, Yahoo, Amazon, PayPal/eBay, Facebook et al. don't start telling your government that they're losing significant revenue because of the behaviour of US intelligence gathering services, then "outsiders" like me are inevitably going to have to find alternative jurisdiction to buy those services (and to create/use replacement services with robust modern anti-nation-state-snooping levels of crypto baked in from the start. Who wants to bet against Silent Circle's Darkmail becoming a serious SMTP replacement because the Brazilian or Equadorian or German or Chinese government mandates it's use nationally - even if it's only done as a political point-scoring "stunt", something like that could be a _major_ win for global internet privacy.)
