QPE and Qt/Embedded are bot released under the GPL -
can you get more purely free and Open Source than
that? The above paragraph hints at all kinds of
dark and closed commercialisms, but the simple
fact is that QPE is open source, and free.
Yes, you can buy a commercial license if you want
to create a closed-source solution. But if that's
your plan, you're hardly likely to buy into the
open source philosophy...
