I would argue that that's a reasonable point to make. Steve Jobs doesn't have a vested interest in seeing Flash die, he has a vested interest in seeing the iPhone platform succeed. If he saw any way Flash could help that, I'm sure he'd be all for it, but he's seen how Adobe's behaved in the past (late with PPC versions, late with OS X versions, late with Intel versions, late with 64-bit versions, crashy Flash, slow Flash, etc.), and he has no interest in subjecting the iPhone to the same issues that the Mac platform has had to endure at the hands of a slow-moving corporation who has little interest in being a good citizen.
I would argue that Jobs is 'neutral' in the sense that he's not supporting anyone else's agenda. He's made his choice based on the facts before him, and while you may not agree with how he got there, I would say that he got there from an initial position of neutrality.
