Wikipedia makes hundreds of millions of dollars a year to run a site that is mostly text. Text put there by unpaid volunteers. Unpaid volunteers that repeatedly request the site stop asking for donations like they’re broke. The executive salaries of the Wikimedia Foundation total $88 million a year.
