Link Details

"This creates an extremely funny niche which makes it very easy to earn money on a Dual Licensed business model. Where your product is basically GPL licensed, but for those wanting to build closed source applications, they can purchase another "closed source enabling" license from you. ... Trolltech was just sold for a billion Norwegian Krones. This is equivalent to about 200 Million Dollars, and all of their products was GPL and Dual Licensed."

Thanks, keep it. I don't want your freedom.

Maybe not, but I am pretty sure you like KDE, KOffice, GTalk, Photoshop, Skype or any of the million or so SW pieces that Trolltech and their product Qt has brought to this planet...
In fact KDE (Linux Window Manager) which is the worlds largest Open Source project is entirely built on top of Qt...

1. QT's GPL is the major stop block for KDE's adoption in the business world (GTK isn't better technically but it's LGPL).
2. QT's sale to Nokia may endanger KDE's future because there's no reason for Nokia to support an (to them) alien platform, the Linux desktop.

Regarding point 1; The entire GNU stack, including GNU/Linux is GPL and that doesn't block for neither GNU nor GNU/Linux in regards to adoption in the business world...
According to the GPL you're free to link against "system things" without being forced into GPL license your own stuff, I'm pretty sure the Window Manager for a Desktop System would be defined as a "system thing"...

What Nokia will do regarding the Linux Qt version, I have no idea, but fact is that Trolltech have signed a "kill deal" with KDE which basically gives away the whole show to KDE if they abandon Qt for KDE...
But I seriously doubt that Nokia would ditch a platform giving them about 70% of all desktop installations of Linux in the world, which I think BTW says something about your "adoption in the business world" point too... ;)

1. The 'GNU stack' is not entirely GPL. Libraries, most prominently the GNU C Library, are LGPL (mostly).

2. Not only KDE is affected by the Nokia-Qt deal but even more commercial customers. They have built their applications on the 'Qt platform' and now have to be worried about their investment. 'Comercial Open Source' doesn't work, at least not for users/customers.

"Commercial Open Source" is increasing in revenue 4 times as fast as "Commercial Closed Source" according to Gartner. Anyway, grown up opinions and you really do have a clue, I'll give you that. I guess this is a case where we just have to agree upon disagreeing ;)
