That has been discussed to death in the "Limits of Interactivity" articles, so I won't delve into that.
The key to that statement is in bold:
They did scream about 3sphere, to be fair. Further, losing on turn 1 because you didn't mull into a FoW has never been fun. At least with Gifts or Uba Stax, you FEEL like you're still playing while you lose.
It is the illusion that you're still in the game when you're actually not. To me, if I had already lost the game then I'd rather my opponent finish me off quickly than waste the time going through formalities.
