Qt Goes LGLP: the Trolltech Saga Attains Closure

There are few commercial programs whose history is more intertwined with the rise of free software than Nokia's Qt toolkit, originally created by the Norwegian company Trolltech. As one of the company's founders, Haarvard Nord, told me nearly ten years ago, when I was writing Rebel Code, Qt began life as a purely proprietary product, but with a free version specifically aimed at free software programmers...

The Trolls Done Good

Once upon a time, there were a bunch of wicked trolls. And then one day, they became good. That, in a nutshell, is the free software story of Trolltech, which produces the Qt toolkit underlying KDE.

Here's a fuller version:

When the K Desktop Environment was first announced in October 1996, it was not greeted with the universal approval that its creator, Matthias Ettrich, had hoped for. Alongside traditionalists who thought that any kind of graphical user interface was “too Windows-like” or just downright “sissy”, there was a deeper concern over the licensing of the underlying toolkit, Trolltech's Qt, which was free as in beer to hackers, but not free as in freedom. As Ettrich told me in 2000:

Everybody joining looked at alternatives [to Qt], and we had a long discussion: Shall we go with Qt? And the result was [we decided] it's the best technical solution if we want to reach the goal that we have.

Since Trolltech refused to adopt the GNU GPL for Qt (at that point: it did later), and since the KDE project refused to drop Qt, many hackers decided that they had to start a rival desktop project that would be truly free. One of the people thinking along these lines was Miguel de Icaza, who ended up leading a global team to create a desktop environment – although that was hardly his original intention:

Initially we were hoping that the existence of the project would make [Trolltech] change their minds, but they didn't. So we just kept working and working until we actually had something to use.

That “something to use” grew into GNOME, a rich, full-featured desktop environment, just as KDE had done, until the free software world found itself with the luxury – some would say liability – of two approaches.

Now it seems that the trolls have really done good:

Trolltech ASA is licensing its Qt cross-platform development framework under the GNU General Public License version 3 (GPL v3), with immediate effect.

Qt is already available under the GPL v2 and will continue to be so in addition to the GPL v3.

The GPL v3 license will make it easy and safe for free software developers to use Trolltech’s Qt with the most recent license framework from the Free Software Foundation. Trolltech hopes that its move will inspire free software projects to use GPL v3 when programming with Qt.

The move to GPL v3 licensing reinforces Trolltech’s strong tradition of giving developers the liberty to create and share software in accordance with the “four freedoms” defined by the Free Software Foundation.

"We decided to add GPL v3 licensing after consulting with both KDE e.V. and the Free Software Foundation," explained Eirik Chambe-Eng, co-founder of Trolltech. "I first read the GNU Manifesto from the Free Software Foundation back in 1987 and it forever shaped the way I viewed software. We at Trolltech are proud to continue serving the free software community by allowing software developers to choose which GPL version they want to use."

"I am very pleased that Trolltech has decided to make Qt available under GPL v3," commented Richard Stallman, author of the GPL and president of The Free Software Foundation. "This will allow parts of KDE to adopt GPL v3, too. Even better, Trolltech has made provisions for a smooth migration to future GPL versions if it approves of them."

What a turnaround. (Via Elkosmas.gr.)

Green...About the Gills

Well, that didn't last long:

Trolltech has discontinued its Linux-based "Greenphone" development platform. Touted upon its introduction as the first Linux-based mobile phone with user-modifiable firmware, the device will be superseded by various third-party products, including not only open phones, but also portable media players, navigation devices, and home automation equipment, the company says.

Ecosystem Network Effects

One of the most heartening signs of maturity within the open source world - both literally and metaphorically - is the growing number of project tie-ups. The latest is Trolltech, which

has integrated Qt, its flagship C++ based cross-platform development framework, with the popular Eclipse Integrated Development Environment (IDE). The C++ integration augments the integration currently available for Qt Jambi – a version of Qt for Java development.

This is a network effect, but writ large, at the ecosystem level.

The Curse of the Open Source IPO

There's a nice round-up of open source IPOs by Matthew Aslett. I'm not sure Trolltech really counts as a full open source company, but I'm probably being a bit harsh given its dual-licensing approach.

What's interesting about this trip down memory lane is that it makes clear just how painful the IPO experience has been for open source companies. A warning, surely, for those that come after.
