Barring the commercial licenses, it's hard to see how Qt could go back to its original licensing model now that it's available under the LGPL.
I also wonder how likely a management buyout would be and how they could make it commercially viable, i.e how many of those with a commercial license would/could quite happily migrate over to the no cost LGPL model.
It would seem to me the main driver for keeping your commercial licence is proper support.
Aye. I did Qt development for a couple of years (all proprietary in-house software). $6000/developer (for about a half-dozen developers) was chump change for us, when you consider that licensing costs for the software that the rest of the company used ran into the millions of dollars. Although we probably could have used Qt legally without paying for a license (everyone in the company had access to the source code, and it was never distributed beyond the company), we paid for the license so we could have the support (which we used).
