Again, my comment that he responded to literally was just making a claim that the iPhone ecosystem is not going to become more open due to voting with one's wallet. Yes, I obviously also think it should be more open, and that's an opinion that someone can strongly disagree with, but that's not what I was saying in the comment he responded to, because whether an action is moral or not is irrelevant to the question of whether it would produce a certain effect.

My point in the comment you responded to is that if person A says "we need to eat more vegetables to be healthy", person B says "no, you will be healthy if you only eat meat", and person C says "I tried only eating meat and I was unhealthy, so I think that's evidence that meat alone might not make you healthy", it's a non-sequitur to respond to person C by saying "it's immoral for you to say someone else should eat vegetables". If you responded to person A saying that, it wouldn't be as weird, but to remain silent when person A and B are debating the health effects of vegetables but then suddenly take issue with person C trying to provide evidence about whether the claims for A and B are correct or when they didn't introduce the topic that you have moral opinions on is very weird.
