You seem to believe that if people quit the company would fail. This is almost assuredly not the case. Instead you would have an equally powerful company with no moral compass whatsoever.

Quitting is a high cost option that denies you any future voice or ability to influence. Jumping straight to that over $200 is unlikely to be an effective tactic.

I am deeply sympathetic with the OP here and believe a refund should absolutely be granted, but if I heard of someone quitting their job in protest over not issuing a $200 refund my initial thought would be "they're an extremist and I should be skeptical of what they say".

I've worked with and known people who have no levels between zero and full meltdown. They're exhausting and I spend as little time around them as possible.
