If using a baseline format was their real argument they wouldn't be supporting a patent encumbered MP3 format for the audio tag, same as Firefox.

IE's historically poor support for PNG is probably the main reason so many sites still use GIFs where PNGs would be better. (Edit: And for that matter, as others have pointed out here, PNG was invented because the owners of the GIF patents threatened to sue the entire Internet.) Browser support for TIFF is an inconsistent mess.
In the case of the img tag, the most common browsers all supported two common formats pretty well (JPEG and GIF), so those two formats became the de-facto baseline image formats organically.
I think the situation with video is similar. If Firefox, Chrome, and Opera (the influential browsers used mainly by the early-adopter, techie crowd) all support one specific codec for HTML5 video, that will become the de-facto baseline video format organically.
The "if you don't fight every battle at once, you have no morals to fight any battle" angle is bullshit. It's agenda-driven juvenile sophistry, and the real world doesn't work like that.
And while I find the WebM initiative questionable (h264 is technically superior and widely supported already), I find it unbelievably boring (and predictable) how it has become a proxy for the iPhone/Android fight. I doubt the Android team had any bearing whatsoever in this decision, and every Android handset out there is just as screwed by the lack of hardware decoding.
Suddenly boring zealots like Gruber and Siegler are experts on web standards and video codecs. What a depressing day. Seriously.
