You're missing my point that they banned anyone from trying to implement Flash in the browser. It's OK to say "we don't want to spend time implementing Flash on iOS", it's another thing entirely to say "no one else is allowed even to try". They're blocking entrants in the Apple app store. If you want to be pedantic about the word "blocking", then swap it with banning instead if you like.
