Apple worked with Google to build a YouTube app that streams videos via h.264 MPEG-4, which is compatible.
Also, Google now offers a version of YouTube that’s completely without Flash. There’s an HTML 5 beta that works with Firefox, Chrome and Safari. They want to ditch Flash as soon as they can too.

Yet Google restricts the WebKit browsers of choice it claims to support.
I'm running Epiphany Trunk which being WebKit Trunk runs HTML5 just fine.
Google isn't looking at generic headers to support, only Firefox, Safari and Google Chrome.
They even offer me a chance to install Google Chrome for Linux.
I only need a WebKit HTML5 ready browser to view their site, yet they are already pulling a Microsoft artificial blocker on the header.
Sad.
