We have no idea that they were sacrificing anything personally. The packages Microsoft offered for people who separated may have been much more generous than what they were currently sitting on. Sure, Altman is a good leader, but Microsoft also has deep pockets.

If anything, staying with what at the time looked like a sinking ship might have been a much larger sacrifice.
