I don't think you can call it free software if you can't compile it.
What good is modifiable source code to users (and others) if compiling
their modifications on non-X platforms requires a commercial license?

False. Read the X Window System license:

You almost have the point.
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". Read the X11 license, the X Consortium
is giving away their software left and right.

I have read the "free" and "professional" Qt licenses. By the way, the
URL is actually http://www.troll.no/
I don't understand why anyone would want to write free software under
someone else's restrictive rules.
A contrasting example: the LGPL. LGPL'ed code stays free, but allows
non-free programs to use it. If you read the LGPL, the FSF doesn't
cover up their motives, they don't mislead people. In fact, when people
(especially Debian) complained that the GPL/LGPL kept bison from freely
being used to develop software, the FSF changed the bison license. They
didn't demand $1470 each time, either.
