Open Source Advocates Hope They Don't Have to Fork Qt (phoronix.com) 137

Posted by EditorDavid from the last-resorts dept.
Phoronix reports on a new concern about Qt, the free and open-source widget toolkit for creating GUIs and cross-platform applications: Wednesday a KDE developer who serves on the board of the KDE Free Qt Foundation commented that The Qt Company is evaluating restricting new releases to paying customers for 12 months. That was said to be under consideration due to COVID19 / coronavirus impacting their finances and needing to boost short-term revenues... [Slashdot editor's note: the comment also claims the Qt Company "says that they are willing to reconsider the approach only if we offer them concessions in other areas."] This comes months after The Qt Company already shifted to make Qt long-term support releases customer-only, among other steps to boost their commercial business at the beginning of the year.

Following all the speculation and concerns from the statement by KDE's Olaf Schmidt-Wischhöfer, The Qt Company released this very brief statement:

There have been discussions on various internet forums about the future of Qt open source in the last two days. The contents do not reflect the views or plans of The Qt Company.

The Qt Company is proud to be committed to its customers, open source, and the Qt governance model.
But in the event of a one-year freeze on free releases, Phoronix now reports, "several individuals and projects are already expressing interest in a Qt fork should it come to it." The hope is first and foremost that The Qt Company and KDE / KDE Free Qt Foundation can reach a mutual agreement without this embargo on future releases, which would effectively close up its development... Among those backing the concept of forking Qt as a last resort if necessary has been developers from consulting firm KDAB, the Qute browser developer, and the QGIS project as one of the leading geographic information system software packages, among many KDE developers themselves.

The mailing list thread is quite active in talking about the possible fork if necessary, including aspects like web-hosting down to what such a fork should be called ("Kt" seems to be a popular choice so far with several different members in the community).
This discussion has been archived. No new comments can be posted.

      Furthermore, while Qt wasn't GPL while KDE was in beta, it WAS free for non-commercial use, which suited the majority of Linux users at the time. Regardless, the KDE Free Qt Foundation secured Qt as open source prior to KDE 1's release.

      Also, it's hilarious that KDE has remained under control of the same foundation since it's creation 20 years ago, with only a fork for the people who wanted to stick with the 3.x base while GNOME has been forked a bazillion times.
