Not really, it&#x27;s just compliance with the license that a piece of software is offered with. Things are no less silly in the world of open source. You are bound to honor the license of the open source software that you use. For instance, if your app links to a GPL library, you are bound to offer your code under the GPL too. However if it links to a BSD-licensed library that does the exact same thing, you don&#x27;t have to.
