The Qt Company itself isn't bound by licenses on the code/documentation, but by a separate contract with the KDE Free Qt Foundation [1]. This document is publicly available and treats the documentation pretty much equal to the code itself. Qt is effin' huge, but it is also at the core of a big and diverse ecosystem. There are many, many users across various industries, including big players and there are companies that offer consulting and development services specifically around Qt. If the Qt Company was to piss enough of these users off, they could easily join forces to create an economically feasible fork. The real trick would be avoiding competing forks, I think.
