Without cloning there would not be anything what we have today and no indie developers as well.
DOOM clones was a thing of past. There were many of them.
Then Diablo clones - Sacred was one of them I liked. Torchlight or Path of Exile should not exist by the logic of article and OP.
If a clone is better and is outperforming original, then clone makers are doing right thing. In the big view on future, patents or any other restrictions on knowledge are only limiting overall progress.
