The problem is how to tell a company that legitimately wants to expand apart from one that was "cheating". That's why this past fee is negotiated on a case-by-case basis. Approach Qt Sales with your proposal and see what they say. If your application is helping the Qt ecosystem, they may not ask for any past fee. > I think this kind of thing should not be automatic at least.

It's not. It's a negotiation with The Qt Company. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel System Software Products _______________________________________________ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
