Looking at the Fedora corpus, there are quite a few programs which link 
against Qt and which are licensed under the GPL, version 2, but not any 
later versions.  If Qt gradually moves new components to the LGPLv3, 
this could threaten the future evolution of these programs.

Fedora is not affected by this because it will likely treat Qt as a 
system library, so that it GPLv2 programs can still use it if its 
license is not GPLv2-compatible, but this interpretation of the system 
library clause in the GPL is not universal.
