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

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

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

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