A team has a spring fail in quali, that partially rips a guys face off through his helmet, is still in the hospital in critical condition with no penalty, while another one has a wheel changing error that causes themselves to be embarrased and lose any hope for a good race result.
Seems like an equitable deal.

Renault did make an error, certainly. But the penalty seems to arise from their failure to act on the knowledge that they'd made that error, putting their driver and others in danger.
