Qt，用来开发 KDE 应用程序 GUI 界面的工具包，最初并不是以完全自由许可证发行的，因为奇趣科技公司（TrollTech）也有商业化的一面。奇趣公司是 Qt 的创造者，那这样为 KDE 开发的专用程序必须获得奇趣公司的许可授权，而且 Qt 的任何升级都必须经过奇趣公司。但是 KDE 软件是一个开源项目，使用 Qt 做开发的做法曾一度在开源界激进分子中激起强烈争议。然而现在 Qt 又在 GPL 许可下重新授权，这些争论也就不复存在了。当然，这是 KDE 发展历程中非常重要的一环。

为什么 KDE 开发人员要选 Qt？

  • Qt 是在 UNIX 平台下最好的图形界面（GUI）开发包。一个桌面环境的成功极度依赖其应用软件。使用 Qt 将会极大地促进应用软件的开发，从而促进 KDE 的发展。
  • Qt 对所有人都是免费的，包括它的代码，为自由软件的开发和发行提供基础。
  • 我们积极地鼓励商业软件公司为 KDE 提供应用软件。这些公司需要成熟、高质量的工具包和技术支持。而在 GPL 下发行的工具包都没有达到这些标准。
  • 重新开发一套在 LGPL 下发行的，与奇趣公司发行质量相当的 Qt 工具包会耗费时间，并且也不会比先开发一个易用、自由的开放性桌面更加重要。

KDE 自由 Qt 基金会

为了解决这个问题，KDE 项目小组和奇趣科技公司共同创立了KDE 自由 Qt 基金会。该基金会保证了 Qt 作为自由开发框架的运作。也就是说，如果奇趣科技公司不再将 Qt 作为自由软件发布，现有的版本会将以 BSD 式的许可证发布 —— 一个与 GPL 或 LGPL 本质上相似但更为宽松的许可证。

This decision to re-release would be moderated by a team of 2 members representing the KDE foundation (unaffiliated with Trolltech) and 2 members from Trolltech to vote. In case of a tie, the KDE vote will gain higher weighting.

Harmony 项目

Those who prioritised the release of an GPL licensed formed the Harmony project - a project to clone Qt under a GPL license. Rapid progress was made during its time and thus gave purists no excuse to reject KDE as a respectable and compliant desktop environment. However this project was depreciated as Trolltech made the decision to re-license Qt under the GPL.
