What was "The Incident" at work that caused an exodus in the work force?

A couple executive-types gathered the more senior developers for an "open" discussion about recruitment and retention. They suggest multiple ideas that would destroy morale (like non-compete clauses, poorly designed work-role pipelines, etc), and all of us suggest against them, and provided alternatives instead (like a shift in direction of certain efforts, more autonomy and less micromanaging, etc). They end up accusing us of not supporting our company's mission and tell us that if we don't agree then they don't want us there and we should just quit. I think after that meeting, only 2 people stayed out of about 30, and hiring numbers have significantly declined.
