My point is that the two largest video distributors both provide and maintain html5 players. The fact that they're putting in so much effort means that there is demand for HTML5 video and that people are actually using it. Furthermore, Apple mobile browsers don't have Flash, and their browser market share is steadily increasing. I don't have any hard figures, but even that says something; Adobe has every reason to release stats that support Flash, which suggests that it those stats don't exist. Either way, HTML5 video adoption is certainly not descreasing, and there are several signs that it is increasing.
