No he didn't. Read the post. This was the first sentence: "Almost two years ago I noticed a strange multitouch problem in Mobile Safari with one of my games."
He should have learned to adapt instead of wait for a change that obviously wasn't going to happen.
So, tell me something: How do you adapt to not receiving an event?
The only choice is to do something completely different, but I can't think of anything that doesn't profoundly change the nature of the game (continuously jump makes a completely different game, use upward motion to jump will have a lot of false positives) and is basically an admission that a game that involves two buttons like this is simply impossible. And that's an unreasonable outcome.
(The continuously jumping game has interesting potential, but it is a different game. Plus I've think I've seen it way back in the day and it's very visually tiring.)
