Back in the day, that's roughly how web developers would frame it when they tried to rationalize making websites that would deliberately refuse to load if the user-agent said something other than "MSIE".

Removing support is a passive action; you accomplish it by just doing nothing. Calling exit() is rather more on the aggressive side.

All that said, good on 'em. I got a decent chuckle.

It's more graceful than the program exiting in a bad way because you passively decided to stop support.
