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.

They spent the last 9 years dismantling their platform one piece at a time. I think they are too committed with their design now to admit they completely screwed up by betting on a vision it never managed to take off, and differently than Microsoft, they don't need to actually listen to their users because they don't have enterprise users they really need to sell their product to (but Red Hat does, and that's why "Gnome Classic" is still around).
