This is purely anecdotal, but I worked at Uber and just looking through the ex-Uber alumni groups I can see a lot of people who I know worked in SF have moved elsewhere (to NYC, LA, Austin, etc.) Also, Uber's workforce is more "decentralized" than most and more spread out throughout the country. I would guess fewer than half of the layoffs were in the Bay Area, especially if this impacted ATG which has a large presence in Pittsburg.
