Altman wanted profit. Board prioritized (rightfully, and to their mission) responsible, non-profit care of AI. Employees now side with Altman out of greed and view the board as denying them their mega payday. Microsoft dangling jobs for employees wanting to jump ship and make as much money possible. This whole thing seems pretty simple: greed (Altman, Microsoft, employees) vs the original non-profit mission (the board).
