Prices are a different thing, but I'm definitely spending my day here adding value.
I suppose the general notion is that the only problem publishers solve is the distribution which is kinda non-value-adding nowadays, but don't think about the editorial process, which needs actual work.
Sure, I think you guys add value. My critique was towards the cost of old papers and the ownership which journals take for published work. You guys need to get paid but the world also needs it's open access to the scientific corpus.
The papers which have very little value adding editorial input do have a harder time legitimizing their slice of the pie, though.
But in theory it's possible, e.g. Facebook's Open Compute Project, it just needs the right kind of funding model.
It's just a matter of finding a way to do it that doesn't jeopardize the entire business.
This isn't throwing the baby out with the bath water, this is people trying to stop this nasty ass bath water from being thrown out because there used to be a baby in it.
