Oh wait:I bolded the important thing for you. So using technology from a company that makes such statements is as safe as using Qt?
1. Mono is not Microsoft technology. It is an ECMA standard.
2. Microsoft has made an irretractable and legally binding promise not to sue anyone implementing the standard.
If Debian considers Mono as free and Canonical feels safe enough to use Mono on its default install, I most definitely have no problem using it.
Mono's GTK# *is* pure GTK+, just like Python's GTK+ bindings are pure GTK+.I just find it funny how Gnome based distros do not include Qt4 apps in default install, because of extra space/dependency issue while on the other hand "controversial" mono is ok even though it is an extra dependency... If they stayed with pure GTK+ apps I would shut up...
Besides, what Qt4 apps are useful enough for a default Gnome install? I can only think of two: VirtualBox and Opera, which definitely don't belong there.
Finally, you might not be aware but every Qt version between 4.x and 4.5 had *completely* broken font rendering. Trolltech took their sweet time fixing the issue, which wasn't deemed as high importance - it just rendered every single Qt4 application completely unusable (KDE included). Now, most people don't really care about typography but my job requires spending 8+ hours a day before a monitor and I absolutely *demand* text to be as perfect as possible on screen.
Thanks but no thanks, Trolltech, I think take my chances with GTK+.
