The system being broken by design doesn’t absolve anyone acting within it from the responsibility of their actions. No one is forcing anyone to game the system as effectively as possible to the detriment of the majority. Acknowledging the system itself is fundamentally broken is pointing out that its design rewards bad actors; bad actors are still acting badly and are responsible for those actions.

When everyone else is willing to get up and leave sitting instead of standing kind of doesn’t hit as hard.
