Why is QT so expensive? 5000+ dollar a year

@kshegunov well, two is more than one ;-)

True enough, although even two is rather pushing it. :)

I miss the days of paying $250 or LESS for an IDE and you're good to go.
You don't have to pay anything for the IDE at all. You mix up Qt (Framework library) and QtCreator (IDE) but I think you know this already since you only registered here to spam around.

I realize this is an old thread, but my words are suited for it.
I use wxWidgets because my understanding is that if I create an application from the Qt Community Edition (no source code changed) that I, let's say, make millions from, the good folks at Qt will have their hands out for a piece of the pie, unlike wxWidgets. True?

No, it's wrong.
Check the licences again.

No, the community edition is licensed under the GPL/LGPL. This is free as in "free speech" and "free beer".

free beer
Did someone mention "free beer"?! 😆
Edit:
To make this comment at least a bit useful:
I would say "free beer" is not comparable to "free Qt". Once you got your beer, you can do whatever you like... drink it, toss it (what monster would do that?!) or mix it with other stuff ("change").
under the free Qt licence, you cannot do whatever you like (in terms of "changes" to the Qt source, for example) -

The meaning of "free speech" has been seriously perverted in 21st century USA, so probably not a good example...and "free beer" usually has strings attached:
- listen to my sad story and pity me
- support my political candidate
- I don't want to get in trouble by myself,
etc.
so perhaps a better analogy, due to the "strings attached" in the GPL.

Sure did! 🍺

That is the whole point of copyleft licenses -- to provide freedoms for the end-users (as opposed to the developers) of software.
Traditionally, proprietary software licenses/EULAs heavily favour the developers but heavily restrict the end-users. It's like the end-users buy a car but are not allowed to tinker with it, pimp it, or even make repairs. The GPL license was created to shift the power balance from the developers to the end-users.
Of course, traditional developers didn't like that so the LGPL was created as a compromise: When using a library (including Qt) under the LGPL, developers are allowed to do whatever they like with their own code; they just need to ensure that the end-users can do whatever they like with the LGPL'ed part.
Once you got your beer, you can do whatever you like... drink it, toss it (what monster would do that?!) or mix it with other stuff ("change").
You can certainly re-mix the Qt source code (or any other LGPL'ed source code) however you like. You just need to share your new brew's recipe with your end-users.

Get better friends; mine never attach strings when they offer me free beer 😜
Anyway, the "speech" and "beer" were there to highlight different types of "free":
- The end-user's freedom to study/modify/share Qt
- The developer's ability to use Qt without forking out money
so perhaps a better analogy, due to the "strings attached" in the GPL.
Got any suggestions?
