215                            No, LinuxSampler will remain open source. Again, the commercial exception is just to
216                            prevent commercial exploitation by third parties that haven't contributed anything to

221                            <h3>I've heard the commercial exception of LinuxSampler was added at a certain version?</h3>
222                            <p class="default">
223                            No, the commercial exception in LinuxSampler's license terms were there since day one.
224                            Even further it's not only there since the very first publicly available CVS
225                            (developer) version of LinuxSampler, that commercial exception was even already in
226                            Benno Senoner's proof of concept code called "EVO", which LinuxSampler was based on.
227                            There was even a rumour that we would have manipulated CVS history to "pretend" this
228                            exception wasn't added at a later point. Needless to say that this rumour is completely
229                            false as well. Think about it! We're a group of developers spread around the world who
230                            work on this project for fun and ideology in our spare time. Most of us contributed to
231                            various other open source / free software projects. Do you seriously think we would
232                            cheat on such an issue? Beside that you certainly find various people completely
233                            unrelated to this project who still have early versions of LinuxSampler and / or EVO
234                            and thus can confirm that this commercial exception was always there.

238                            <h3>Doesn't LinuxSampler illegally link against libgig?</h3>
239                            <p class="default">
240                            No! LinuxSampler does not "illegally" link against libgig, since the copyright holder
241                            (in this case of libgig) has all rights of his work and thus is not bound to his own
242                            license terms. The sole purpose of license terms is to grant other people certain
243                            rights to use the work.

248                            <p class="default">
249                            No, the only library LinuxSampler links to that has license restrictions regarding
250                            linking is libgig (<a href="#ls_breaking_libgig_license">see above</a>). Especially
251                            LinuxSampler does not break Qt's license terms, since it does not link against Qt at
