I'm not a working scientist - I have no paid-for University access to a variety of journals or other such connections, nor do I know the intricate details of how research is published. What I do know is that I'm a citizen helping to fund much of this work, and access to primary literature is critically important to make informed decisions about our future. The academics are paid a salary to produce findings, not to sell individual copies (unlike the music industry comparisons). While I'm willing to pay something, I can't be expected to pay the huge costs to access individual papers that are demanded today. Open access journals like PLOS are fantastic, but it's an unfortunate reality that much of the quality research is published on platforms that charge $30 for a paper. Until this changes, sci-hub is my answer.
