Its really annoying when it happens like with Miami/Mui etc but when you stop and think about it after all its the software authors programm/game/whatever and unless it specialy says something in the license he is free to do wtf he wants to do and end it or kill it when he see fit even if its bad for "potential" customers! the regged customers already have theyre versions only crapy thing for them is the perhaps promised updates if there was any.
