Qt being as defined in the commercial license agreement, i.e. including tools and framework. This was what the person initiating this mail thread asked about. I do agree that it gets complex when one starts including items created by an independent third party. This is at the moment not listed as an allowed case, even though it is not something we specifically aimed to prevent.
I understand the underlying reasoning 100%, but clarity is important
here, and the ones I brought forward aren't some "far fetched"
In a product developed with Qt commercial, anyone is going to using a
bunch of non-Qt libraries, for instance coming with any basic Linux
installation (e.g. glibc, libstdc++, ICU, whatever). Maybe some ad-hoc
ones, e.g. Boost. How can one be sure that none of those has been
developed using GPL Qt Creator? Should one just "live with" the
possibility of infringing the commercial license, because TQC is just
not interested at chasing this case down?
