photomatt made a smart move to incentivize the exit of employees who disagreed with him on this important issue (as it would have festered in the company), but I think he offered them too much money.
I agree - he's facing a lot of criticism for reducing diversity or difference of opinion, but you don't promote this in context of your core values and conceptual integrity. You have private debate, reach a decision and then everyone publicly supports the direction. If you don't believe in the decision or can't support it, you need to leave.
