How? Whatever does Google Search have to do with YouTube? Google Search is not affected in any way what so ever by neither Google's nor Mozilla's love or hate for h.264. Also, YouTube is fully enjoyable with Flash. No matter how I twist and turn your response, I just can't see the red line you're trying to draw here.
Yes, weak critical thinking does seem to be a problem here. Let me collapse the three simple implications for you down to "All of Mozilla's money comes from a known h264 supporter." If you're going to make some sort of bizarre conspiracy theory about money making Mozilla hypocrites, then following that up with "And therefore Mozilla is not going to support h264" just doesn't make any sense whatsoever. If they were slaves of their money, they would be supporting h264 loudly; this is sticking a finger in the eye of their money source, not kowtowing to them.
Google owns YouTube, the world's largest video site.
YouTube is using h264.
If your theory was correct that Mozilla is solely concerned with money, your theory would predict that they would support h264, rabidly.
