I'm with a multinational multibillion dollar company and entire teams will quit on core products all the time. The VPs make up stats and dodge questions on calls. The reality is that it's actually never really hurt the company because the deals that are being made are millions of dollars and delivery is guaranteed by insanely complex requirements and app certifications that alternative offerings can't meet.

Agreed. A company that would enable a work environment that fosters a mass exodus would be unlikely to feel accountable to any remaining employees.
