Engineers leaving, being fired or just being time, can happen to early engineers that made the company great as it changes. Changes like this are usually around growing pains and when power is transferred from engineers to the money/business or growth from small to medium or medium to large. Companies and developers evolve, sometimes they aren't as nice a fit after they do. Companies always run off good processes, but when you start hearing about new or needing changes to 'processes' driven by new VPs or Directors, usually that ocean is red and you need to move to blue seas and oceans again. Zach is probably a startup, product and research and development type of developer. He should stay at smaller companies or start up his own, I am sure he could get funding quickly. I'd even be for an additional github competitor though that could be un-interesting after this for him.
