GM's can be replaced though, and players could just keep roleplaying even if the GM wishes it closed.
In other words...
"OOC conflict today, player vs player PM wars. The GM is afraid of us. We have seen their true face. The OOC are extended arguments and full of yelling and when the hurt feelings finally scab over, the GM will lose hope. The accumulated slowness of all the GM's un-interest and absentees will foam up at their waist, and the GM will look up and shout 'End the RP!' and the players shall whisper 'No.'".
