What’s wrong with the LGPL? If you dynamically link them, then you don’t need to open source your product. It’s only a problem if you want to statically link.
My point is that my company would be willing to pay for Qt (and it did pay in the past), but not that much. In the current situation they don't get any money from us at all.
This is a much greater hassle than just linking dynamically, so we don't do it.
