this is a joke. If I modify or enhance QT - then they can compel me to contribute such modifications to the community. But how can they compel me to release software written using QT? and further compel me to release it under the GPL only??
Sorry, no joke here. Only if you sell your modifications/enhancements are you required to release the source code. Keep it to yourself and Qt wouldn't give a damn.
"The Open Source Edition is freely available for the development of Open Source software governed by the GNU General Public License versions 2 and 3 ("GPL")."
apparently this means that QT itself is not released under the GPL - the open source edition is released to 'develop open source software governed by the GPL ...'
huh? The operative word in your statement is "apparently" - and I can assure you that your understanding is wrong, unless you have your own English grammar and semantics.
So I cannot use that to develop software I release under, say, BSD license!. So what license is QT released under?
Sure, you can't, if you *choose* the GPL path! With such possible mixing, we'd have had dtrace and ZFS for Linux long back! BSD and GPL don't mix. To answer your question, based on your above cut-and-paste-from-trolltech: QT is available under multiple licenses (GPL v2, v3, and its proprietary license.)
