AFAIK the reason was constant juggling with codecs on Apple side as mentioned here, so all was rendered by software at the end on macs. The fairly tale of just Apple trying hard to make flash work on their hardware and Adobe sabotaging their own product on a major platform doesn't make any sense from business or even just logical point of view. Some companies, or even countries simply never properly acknowledge errors or mistakes on their side, it certainly looks like the case here (and I doubt anybody relevant could speak here due to NDAs or still actively employed).
