$300 down to $80 in a span of a couple of months on news of a known/expected 3-5% of users leaving, while profits are increased, I would say count as "disproportionately large". The way insiders work is like this... If they know they need to get out, but can't due to SEC insider rules (you can't sell a stock about to tank "just because", without getting in trouble later on), they take the first public opportunity to do so... On the release of any public bad news, that way their asses are covered.
