still limits it to qt apps only. gtk, xul, fltk, efl, raw xlib... need major
work. an x11 environment can ALSO run the qt apps... so it's a superset.

no - i meant either i accept GPL, OR i pay for a license TO nokia to AVOID the
GPL infecting my software. me paying for a license to not mean i thus obviously
am going to make my library app closed and force people to pay for it, but
the reality that i have to fork out money to ship something licensed as NOT
being GPL, invariably will lead to having to charge for it.

how does this limit them? they have access t more apps, more toolkits and more
software and have the CHOICE to choose their applications, be they open, or
closed, GPL, LGPL, MIT-X11, BSD etc. etc. etc. how does this seem like less
freedom to you?

i know. but as they invariably use QT, GPL superceeds LGPL in terms of being
more restrictive.
