I don't think for a second that Adobe's decision was motivated by the open nature of HTML5 itself. If anything being open is a downside for Adobe in their current market position. I don't think the "poor technical choices" of their product are explained by its proprietary nature (MP3, H264 are example of the contrary) but they are for sure the reason they're moving away from it.
