I don't think it's just that.

- Amazon's back-loaded vesting costs them top talent.

- Amazon's pip culture is notorious. When Amazon managers get hired at other companies people immediately consider it a turning point for the company turning to crap.

- Commuting is a killer for a lot of people. You either live somewhere expensive and have a short commute, or live somewhere less desirable but have a longer commute.

This is definitely a big part. Some of that was listed in the article, but it's a big barrier when you look at COL in places like SLU Seattle. Then you have the terrible vesting schedule. Now this. It's no wonder people are looking for work elsewhere, and really I think this is just the final straw for many.
