That said, better encryption will raise the cost of NSA's surveillance which might eventually lead to policy reform (when budget hawks are forced to act). And it might mean their dragnets have to be more targeted which could slow the expanding the definition of "terrorist".
I think the most effective actions would be to make the public outraged over cracked encryption and surveillance. And even with all these leaks, that hasn't happened IMO (debatable I know). Outrage would happen if people understood how this has real-life effects. Storytelling is what's needed, not white-papers and tech blogs.
edit: wanted to add that Bruce Schneier gave an excellent talk on the topic of your question, https://www.youtube.com/watch?v=3v9t_IoOgyI
