Yeah, because people magically become mischievous spies for the competitor the moment they give notice.
All this time they were job-hunting, doing interviews, and negotiating offers, it was just for fun, and they were still the "good guys". But the moment they communicate a decision to leave that they actually made a long time ago, when they started looking for another job, they automatically become Osama Bin Laden.
Sure, it makes a lot of sense...
