But how can Google justify dropping support for H.264, but not Flash (which also uses H.264 for video)? Simple, Adobe is also one of the WebM partners and will support WebM technologies inside Flash. Yup, Flash is siding with Google on this one. So the battle lines here are really between Google and Apple, which is still sticking with H.264 (the non-Flash variety). Just when it looked like H.264 was winning too.
