I agree completely. If I made a commercial app I would pay.

My concern is that I don't trust Qt Company now to not change the rules on me later, or hike the price, etc. I would choose Qt for commercial solely because I already know it from building FLOSS apps. If I need to learn something else for FLOSS, I'm not going to stick with Qt. There's limited space in my brain for expertise and I want something that will meet all needs.

Qt is amazing and I love it, but an amazing thing I love but can't use/rely on isn't worth much.
