I do understand it has been broken let me explain why if itachi wished it would of never been broken. Also like all my post with facts and manga pages the pages are hidden in spoilers for your convenience.
1: It takes about 1 second in real time for tsukuyomi to take its full affect.
2: It takes a second for a jinchurriki to realize he is in a genjutsu. Therefore tsukuyomi is unbreakable by a bijuu since the entire genjutsu time is 1 second.
3: Same thing applies to sasuke as it only takes one second and will only drag on if itachi wishes so. Also another thing to note is itachi lied when he said only someone with the same blood can break his tsukuyomi as sasuke resorted to using his cursed seal(which is chakra from orochimaru) to break it. One of the ways to break genjutsu is to input chakra from a different source into that person thus disrupting the genjutsu and returning the normal flow of chakra.
