The same community that hates patent trolls continued to use gif and MP3 for many years, so I'm not sure why use of H264 would surprise you. And are people really 'in love' with it? All I see is people who prefer the clearly technically superior option. Not to mention the fact that many of us live in places where software patents are not relevant, and don't feel inclined to use inferior technology just because of the idiocies of the US legal system.
