Authors or their institutions don't get a penny from paywalled papers either. Oftentimes they have to pay to publish. Authors choose the titles, sometimes reviewers (not paid a dime either) can demand changes to the title, and the academic editor (paid ziltch too) can require the changes. This doesn't apply to arXiv though, as it is not peer reviewed nor edited and is funded by various institutions. Admittedly the academic publishing system is so corrupt that it's hard to phantom, so it's easy to misunderstand it. Typically you do pay for the papers (and publisher profits), either through taxes or inflated product prices.
