A feature, not a bug. Apple has single-handedly helped push back on the scourge of Flash-heavy web sites. 75M people out there in web-land don't and won't do Flash. That's enough to force web designers to pay attention to some of the newer HTML5 features that can replace things that you formerly needed Flash to accomplish.

(The never-ending list of Flash security flaws, alone, is reason enough to want it to go away.)
