Its old news bro, the last one was Bogomil who left for Diane's startup which I also posted a while back.
My take on it is that with the re-alignment there are just too many hands on deck at least for management.
As for the engineering side, they are making steps to retain talent. My co-workers who are still there confirmed that they gave a lot of merit raises + bonuses for the star performers this year. Kinda makes me regret leaving prematurely, could have vested a bunch more RSUs which I can sell now at 82... oh well live goes on
