He was pissed at his cushy Distinguished Engineer role being canned. All those folk were. Oracle offered all Principal and above an IC4 only role to prove their worth. This is why he was pissed.
I've heard some crazy things about myself over the years, but this might just take the cake! As I have said before[0], Oracle gave me many, many reasons to leave -- none of which had anything to do with the way they were dealing with me personally. If you don't mind me asking (and just because I'm so mesmerized that someone could come away with something so wildly wrong): where did you get this notion?! Did someone tell you this? Did you come up with it on your own?
Sure, but that didn't have anything to do with my departure. I didn't particularly care about the title -- I was always much more concerned with the problems I was solving, the people I was solving them with, and the customers that we served. And honestly, it was Oracle's behavior with respect to the last of these -- namely, Oracle's total disdain for its customers -- that I just couldn't stomach. In short, I found myself ashamed of my employer -- and that's why I left.
