I'd be fine with it being open. I'm just very happy to see a vendor push website operators to not completely rely on Flash, a proprietary plugin controlled by Adobe. If Adobe were to open up the Flash runtime, I would have zero issue with it, and I'd even wager that Apple would turn themselves around on the issue. To have the entire web at the mercy of Adobe is a bit much for me to swallow. Flash is great at a few things, but websites completely reliant on it needed a swift kick in the pants.
