Apple employees should have kidnapped Alan Dye from his office and deposited him on Facebook's doorstep wrapped up in a straightjacket with ribbons and a bow years ago before he finally left voluntarily.
Using Dye as a scapegoat feels like cope. The rest of the executives were fully content with this effort, and in the end he wasn't even forced out. There's no evidence that Apple will correct its course without him.
Like the Hong-Kong guy in The Dark Knight!
