 - OSL allows you to link to our libraries without needing to disclose your own project, which might be useful if you want to use the TS3Client as a library.
 - If you create plugins you do not have to make them public like in GPL. (Although we would be happier if you shared them :)
 - With OSL we want to allow you providing the TS3AB as a service (even commercially). We do not want the software to be sold but the service. We want this software to be free for everyone.
