The GPL requires that redistributors of BusyBox ensure that every downstream recipient is given access to the program's source code. Monsoon Multimedia says on its Web site that its products and firmware contain BusyBox, but it has not provided any recipients with access to the underlying source code, the SFLC says. "Free software licenses such as the GPL exist to protect the freedom of computer users. If we don't ensure that these licenses are respected, then they will not be able to achieve their goal," said Eben Moglen, founding director of SFLC. "Our goal is simply to ensure that Monsoon Multimedia complies with the terms of the GPL," he said.
