But the OA is about Adobe and HTML. Of course, it's not so much that they'll jump to the tech that has displaced them, it's more the marketing language (which, again, I know everyone's at it) suggests "yeah, cool, we always wanted this one to win, honest". They even give a history lesson on the site, and that's not the history I remember.
Poor engineering, that's aimed more at Flex than Flash. I spent many months suffering at the hands of Flex and the Adobe IDE. We implemented exactly the same app in both Flex and Java, Flex and its environment were painful, relatively.
Companies will protect their own interests, but both I personally view Adobe's decision to drop the SVG plugin, and Microsoft's decision to enforce their own standard on IE as de facto, as having put a general drag on what could and can be achieved in browsers. They're entitled to do so, but I think the decisions have been detrimental to the Internet population as whole, that's all.
