Sure. In the case of Qt, it was very expensive but well worth paying for because it does a good job. The LGPL stuff is important because it provides us with an "out" if the Qt company goes crazy with prices.
Avoiding the "out" makes me not want to make use of the new modules. And the hassle of audits makes be question the cost of the inconvenience to me, the dev, of having a license.
It's outrageously expensive. And you can't just buy what you really need, just all or nothing. In many projects I only need Qt Core; for that I would have to buy a license for everything from these people with a far worse contract than LGPL and pay royalties. No thanks.
