Presumably, anyone at a staff+ level position in big tech, is likely influential and their word carries weight. So, I'm not sure how this is a pro or con for joining Amazon.

If anything, someone at that level earns so much money, and has so much unvested stock waiting for them, that even if they grow tired of the work, or disagree with its direction, they are unable to leave for something more fulfilling.

Being forced into the office 5 days a week might be enough to force you to reconsider though?! Maybe?!
