This may have been the straw that broke the camel's back, but it's probably not the only reason he was let go. (It does make for a great cover story though)

Let's just say almost all the senior leadership and a huge number of employees left the team or Google completely before this came out. Almost every single person I know that hasn't left is strongly considering it.

I personally left right as Amr joined, but even in the few months of overlap I had it was obvious that he was a terrible fit as a DevRel VP...
