Wrong. Open Source does not have to bend the knee to whatever proprietary license you can dream up and shove into your code base.
>Source code: The program must include source code, and must allow distribution in source code as well as compiled form. Where some form of a product is not distributed with source code, there must be a well-publicized means of obtaining the source code for no more than a reasonable reproduction cost preferably, downloading via the Internet without charge. The source code must be the preferred form in which a programmer would modify the program. Deliberately obfuscated source code is not allowed. Intermediate forms such as the output of a preprocessor or translator are not allowed.
Does this apply to Linux? Check.
>Derived works: The license must allow modifications and derived works, and must allow them to be distributed under the same terms as the license of the original software.
