I hate to risk sounding like I'm beating a dead horse, but when I hear this I flash back to Attack Surface by Cory Doctorow. I interpreted his message in that book as something approximately like "you can't out-tech the bad guys", where "bad guys" can mean government surveillance agencies (probably more what he had in mind) OR "big corporations trying to control your life" (this may be me extrapolating). But even if I'm over-generalizing a bit, I think the point still stands.
"We" (open source advocates / hackers / hobbyists / makers / whatever) can't win on just tech alone. We have to use the legislative process, political pressure, social pressure, whatever, to achieve our goals. And so we should use our superior knowledge of technology to support doing that. So don't just think "how can I hack my phone to use an open source OS" but think "How can I help use technology to influence the outcome of the next election, and elect candidates who really represent the things I care about?" or "How can I help use technology to stir up enough activists making enough noise to persuade my bank to let me access my account using a non-proprietary OS", etc.
Now I'm not saying any of this is easy. By no means. Just suggesting that we need to at least approach things with that mindset in view to some extent.
