Turning Off Ads in Parallels

Parallels apparently serves ads to their customers, who already paid $80 for the software. The only way to turn them off is through an arcane Terminal command (defaults write com.parallels.Parallels\ Desktop ProductPromo.ForcePromoOff -bool YES according to Reddit). Any reference to that preference setting gets deleted by Parallels Support if it’s posted in the related forum thread. Via John Gruber.
