Yea, that was my understanding of it also. I think they are trying to make the argument that once the your code is written under LGPL, its LGPL forever and can't have another license.

[lultimouomo]

Your code is never under the LGPL though; you are free to license your code as you please. It's the binary you release that being linked to a LGPL library is subject to its conditions.

If that was true, then QT would violate this principle itself and could not sell you a commercial license.

Qt doesn't violate this principle, cause it is double licensed, Digia is just not using the LGPL version.
