I'm certain he's aware of it. I'm certain he's also aware that you can easily get to porn on an iPhone using Mobile Safari. Much more easily than installing an non-Market app like Mikandi and then using it to find porn. Hell there are even a rather astonishing number of porn sites that seem to specialize in iPhone optimized content.

So given all that, you have to wonder why does he even bother to mention Android at all, especially considering that the Android Market prohibits porn just like the Apple App store. You've got to be incredibly naive, or deliberately disingenuous to claim it doesn't sound like a deliberate attempt to slander his competition. Kind of like the old political routine of asking your opponent when he stopped beating his wife. :-)
