fully agree.
the power struggle does not have no affect on people leaving, but its not the primary reason.
at the end of the day people are doing a job. and if you had the option to work in an enviroment where the people in charge are fighting, (or being reported to be fighting in the media) or not, then the choice becomes easy.
imagine for a second there is no internal conflict, but the media reports say there is. now Joe soap goes home for summer break and his friends in the pub are asking him all these questions. then some other team comes in and asks him to come to them, get a promotion more pay and no need to answer those questions down at the pub? no brainer to leave right?
