I'm a big Apple fan, but there's no way anyone can say that one comment on one application is a sign of Apple becoming more "open". Still silence on Google Voice and dozens or hundreds of other randomly removed applications which might be similar to what Apple has released.
And to be clear, Apple has a monopoly on the iPhone market. It's not illegal, but it's a fact. And they use this monopoly power to control the iPhone application market. Whether they are abusing that power is a matter for lawyers.
Yeah and every company has a monopoly on every product they sell.
