I think you have a different definition of "open source" than I do at least. LGPL is (IMHO) a true open source license.

I agree though that some licensing changes would really help them grow. I think they've hurt long term adoption in exchange for short term revenue. I don't blame them, baby needs new shoes after all, but as a huge fan of Qt I would love to see them become a standard. The product is good enough that they deserve it, but the license can be a bit scary for people who aren't already familiar with it.
