LGPLv3 is useless for people developing proprietary applications, which was what I was answering to. Those people want LGPLv2.1, which is how Qt used to be licensed during Nokia times.
How is the LGPLv3 materially different from LGPLv2.1? It's perfectly possible to use Qt under LGPLv3 in a closed source program with dynamic linking without much fuss.
