The most obvious solution would be to boycott all DRM encumbered content. That could certainly work at a HN level, but the money of the billions of other people who don't really understand what DRM is still speaks quite loudly.
You could educate and advocate a broader boycott, but in practise what you would be asking people to do would be to forgo the majority of mainstream pop culture. Basically a tragedy of the commons.
The only other solution would be to propose legislation that would make illegal or punish those who integrate DRM. The only political party in the UK who would be open to such an idea would be the pirate party who will never win a general election because there are very few people to whom copyright law is the #1 hotbutton political issue.
