But the implication that Troll prevents authors from redistributing their own software free-of-charge on other platforms and instead sells it as part of their toolkit isn't true. If an author owns a license, or finds someone with a license willing to compile and link, the software and dynamic libs can be distributed without charge. <snip> > > > -Changes and patches to the Qt library itself can't be distributed > > without Troll Tech first integrating them into their product and > > "blessing" them.

My words were misleading here. I meant "(This is true for Qt under the X Windows platform as well.)"

"free" means different things to different people. Personally, I like the Debian/Gnu definition. But if someone else uses it in another way, that doesn't mean that they are scammers and are trying to mislead us. Qt is a commercial software product. There are restrictions on the use of their product - either buy the expensive commercial license, or don't sell your software - and buy the expensive commercial license if you want to compile for a non X-Windows platform. But calling Qt a Scam is a bit strong. I think they make it clear that they want to make money selling their product. I think it is also clear that they want to use their "Free-Software" License to encourage people to use and learn their product so they can sell more commercial licenses later. > > A big part of the word "free" is that it doesn't mean "use this unless > you want to write Windows95 software", or "as long as you don't try to > make a buck, you can use this".
