That web page is incorrect. (And not just because it calls the GPL the "GNU Public License".)

The Qt libraries are available under the recipient's choice of the QPL or the GNU GPL. Software licensed under the GNU General Public License can be used and included and distributed in commercial software; it explicitly allows this. What it does not allow is the restriction of users' freedoms beyond the existing restrictions in the GNU GPL.

The fact that the author of the above web page doesn't know the difference between "commercial" and "proprietary" does not change the terms of the GNU GPL under which Trolltech have released their software.
