You mean Qt? Isn't that mostly LGPL 3.0? In what way is the license violated?
You may not distribute a LGPL program as part of a single static binary without the corresponding source to the whole thing or object files for the parts so that you could link with a modified version of the LGPLed component.
Well, without providing the source upon reasonable demand. Did you make a reasonable demand for the source? Was it rebuffed?
Do you suppose all those digital toasters available at WalMart, with embedded graphics built upon Qt, ship with a full copy of the source code in the box? Or do the manufacturers just summarily fulfill requests for source in a reasonable fashion?
But in the moment, it's a good thing all the source is available on the repository, hunh?
