This is certainly distribution.<p>If the `checkBrowser` function uses GPL&#x27;d code, then anything that calls `checkBrowser` in turn must be licensed under the GPL.<p>But that doesn&#x27;t mean that this Comcast code _is_ licensed under the GPL.  That means that the copyright owner (brainjar) can take action against Comcast, and tell them to either stop using their code, or change the license.<p>They&#x27;d just stop using the code.
