They already celebrated their earnings in the past, people got bonus or raises or promos on their "performance" using the fruits of their bad behavior. Probably there is different leadership now. The new leadership can use these things to explain any slow quarter, then they try to write off any problems they have now and combine it with this problem (and blame the old person). You see this cycle again and again. Until companies are killed or leadership is fired, and loses their potential for future employment/mayhem, goes to jail - if there is no immediate serious personal repercussions or the company might die, then there won't be much change.
