Commercial interests will be expected to have a say, but shouldn't be the ones to decide the future of the internet. However, money talks and i don't expect the internet to remain free unless we as stakeholders do something about it.
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.
For example the ultimate form of DRM is the iOS style where code must be explicitly white listed by some authority in order to execute. This is potentially bad for all kinds of reasons that are nothing to do with piracy.
However any system that relies on absolute centralised trust is vulnerable in a variety of ways.
For example if you were to develop a system that allows for secure , encrypted communications between 2 parties such as GPG.
The platform vendor can enforce a policy that any such software must include a backdoor for their own use, that of law enforcement or for their advertising partners.
Whether such a policy is implemented now or not is not so much the issue, it is that such a policy could very easily be enforced in the future.
As long as open platforms are viable and available the issue is less urgent since people can opt to use these instead.
However when you have powerful companies with lobbying might such as the various content industries who have their own reasons for preferring such a model it becomes a little scary.
I certainly know hippy type people who would care about stuff like this at an ideological level but are not technical enough to understand the specifics and would struggle to identify whether the video they are playing on their computer is DRM protected or not.
