Well the skype plugin itself is open and the source code is available
so the plugin does not violate like the mebeam plugin. If it was like
that pretty much every protocol but xmpp iirc would be in jeopardy.
You have to understand that regardless of if the protocol itself is
closed source and violates the gpl doesn't matter as long as the
plugin itself being used is open and doesn't violate the gpl. Like I
said pretty much every protocol used in pidgin is a closed source
backwards engineered protocols.

 Thank you,
