Frankly, technobabble (or other x-babble) is among the scourges of science fiction as a genre, and cannot really be said to fill plot holes.

That aside, I agree - there unquestionably are plot holes in the ending, and Joker's actions are among the top of the list. All I was saying is that some of what certain fans have been going on about are really insignificant nitpicks, not that everything is. It's very hard to see how anyone could argue that there are no plot holes in the ending whatsoever.
