2. You submit novel research to the best journal you think will publish it.
3. The editor (the only person involved actually paid by the journal) invites other researchers to volunteer their time to peer review your research.
4. Assuming your research bears up under scrutiny and the peer reviewers are not actually competitors who decide to filibuster (this happens), your paper passes peer review.
5. Congratulations! The journal agrees to publish your novel research. For this, you must pay the journal. They do not pay you. You pay them. Color figures in the paper version nobody reads cost thousands extra.
6. Having been paid by you to publish your work, the journal sells your paper at exorbitant prices to university libraries (unless you paid them lots extra to just make it available for free).
Taxes pay researchers to pay journals and taxes pay for university libraries to pay journals. Why on Earth do intelligent researchers (or taxpayers) put up with this crap? Being published in a good journal bumps up your impact factor and helps you win more grant money. If high impact factor journals go out of business because of piracy, others will just take their place.
In short, pirates screwing over journals doesn't hurt researchers in the least. Shaking up the parasitic journal biz is actually long overdue. Journals put in only a tiny percentage of the labor involved in putting a paper through peer-review, but they soak everyone involved for massive amounts of time and money. It's time they died.
