People make decisions between proprietary (closed-source) software and open-source software daily without even realizing it. Do you own an Android phone or an iPhone? Are you browsing the internet with the Safari browser or Firefox? Internet Explorer or Chrome? Open-source software has a significant place in the world and in our lives, and that is especially true when it comes to all-things-internet-related. Chrome, Firefox, and the new Microsoft Edge browser are all open-source. As is the Android mobile operating system. At least a third (probably significantly more than that) of all websites are hosted on servers running Linux, an open-source operating system, and more than a third of all websites run on WordPress and many more are on Drupal, Magento, Joomla, and other open-source content management systems.
