The whole article really has nothing to do with Flash. Did you even read it? It's about Jobs saying "this is bad for reasons X, Y, and Z", without acknowledging that Apple is guilty of the exact same BS.
Example - he basically says Adobe sucks because they just finally got around to releasing a full "Cocoa" binary for CS5. And yet Apple has the same problems. The Finder was Carbon until Snow Leopard was released, less than a year ago. And iTunes, arguably their biggest app, is still Carbon. Yet somehow because Adobe still had Carbon apps as of a few weeks ago, they are evil.
