[Interest] Qt Creator licensing for companies with Qt Commercial developers

[Andy]

That makes no sense. Your license prevents a company from using an
open-source tool? It says "if you license our stuff you cannot use the
open-source tool X"?

This whole thread is yet another great example of where the Qt Company is
totally tone-deaf.

Nobody understands your licensing. You have fewer people using Qt and
Qt-based things because of this.
