employment is just a business transaction, i don't believe people should tie their sense of integrity to how they interact with an organization that would fire you with zero notice and not even tell you why
Integrity doesn't vary based on the actions of other people.
A better move would be to use the networking opportunity to find other high-performance people who don't like the BS, and form a productish-consultingish worker-owned co-op to replace the soulless, erratic corporation with a more stable, humane environment.
