You managed to reply to my comment without confronting its central thesis. Steve Jobs claims that Adobe's Flash technology is proprietary. This is a fact. Flash IS proprietary. However, Steve also claims that HTML5 (which includes H.264 for video playback) is an "open standard". His words:
This is undeniably false. H.264 is a proprietary codec which must be licensed from MPEG LA. It is not "open" in any sense whatsoever. Steve Jobs is, therefore, a liar.
Except what you said is false. H.264 is NOT part of HTML5 (which is why Firefox can continue supporting it, without being non-open).
And as Steve correctly states, it is an Industry Standard (which is also true, and not true of Flash).
Also, the only "open" alternative to H.264 until a couple of weeks ago was Ogg-Theora. This was a non-starter because of mainly extremely poor HW support, and almost non-existent quantity of content (how much of Youtube is Theora? Ans: 0%).
2-3 weeks ago, Google released VP8 as open-source, however, since that was only a couple of weeks ago, there is no content in that format, and also, no hardware (or decent software) support for it. It will take at least a few years before it becomes popular, so is not a viable choice right now.
Steve Jobs is spot on here.
