Introduction Open source Unix has taken over the embedded systems market. Linux, BSD, and other open source operating systems now power over 50% of new embedded devices. And it's easy to see why: they deliver better functionality, at lower cost, than proprietary systems. Recently, however, some have called into question the use of Linux in embedded applications due to the strictures of Linux's GPL license, which requires that any source code that is changed also be released free of charge. Unfortunately, many of these "critiques" are merely spreading fear, uncertainty, and doubt. However, the GPL does have important legal requirements which may be of critical importance, depending on your business. At Wasabi Systems, we use GPL software, BSD-licensed software, and proprietary software. Since our customers frequently choose our solutions because we offer a range of licensing options, our legal department, headed by Jay Michaelson, a widely-published expert on software licensing, has created this website to separate myth from fact for those considering Linux or BSD. On this site, you will find a short "Licensing 101" guide to when the GPL requires you to share code, and when it doesn't. You'll find out exactly which business uses the GPL really affects and which it doesn't. You'll learn how the The Sarbanes-Oxley Act changes the open source landscape by making GPL violations a federal crime. And you'll learn how Loadable Kernel Modules may be the riskiest Linux bet of all. We welcome your comments and suggestions for how to improve this site, as well as external links and resources you think may be of interest to our visitors. Open source software carries both benefits and costs, and we hope this webpage helps you make the right decision for your business.
