I'm not using my @kernel.org address except for kernel issues and I'm 
not using a company address in linux-kernel discussions.

Mailing lists of a project or a company are something completely 
different from using a project or company address outside of the 
project.

Wine is licenced under the terms of the LGPL.

ReactOS is licenced under the terms of the GPL with a licence 
exception for runtime linking of non-free modules.

QEMU is licenced under the terms of the GPL with a licence exception for 
runtime linking with libqemu.a.

GNU classpath (and libgcj) are licenced under the terms of the GPL with 
a licence exception for runtime linking with it.

As you can see, all of the above explicitely address this issue.

The only program from your list that has a fishy licencing is mplayer.
