I was a little peeved, but looking back not so much. I was receiving pressure and what I felt were conflicting orders from the CTO and CEO, and any company that lets someone go for showing initiative is not a place I want to work. I found a more fitting job doing high-speed creative product prototyping (where they want that kind of thing) afterwords, and for more money.
(It was a startup, and I now see it as having had some funny politics going on. I also think that one of the co-founders wanted me gone since I didn't graduate from one of the "right schools." He was a huge school-snob.)
