If the same software performs better on other platforms then the one platform that has the biggest problems should do something as well, that's what I am saying.
It performs better on one other platform. In my experience, Flash is pretty awful anywhere besides Windows.
And I'm not sure what you mean when you say "the one platform that has the biggest problems should do something as well." Apple and many Linux supporters are doing something — they're aggressively pushing HTML5 and related technologies as an alternative to Flash, over which they have no control.
