I also think you might benefit from rereading the context here; someone said that government regulation is needed to make the iPhone ecosystem open, and someone else disagreed on the basis that voting with one's wallet is a viable alternative. I disagreed with that disagreement, arguing that voting with one's wallet doesn't produce the change that the original commenter said regulation was needed for; telling me "that's not what voting with your wallet does" is redundant, because that's literally what I was already saying. You're certainly entitled to disagree with my opinion that making the ecosystem more open is a desirable goal, but that's not a premise I introduced here, so if disagreeing with that is your intention, it's unclear to me why you picked out my comment as the one to express that when the original statement of that goal was several parent comments up from mine.

Trying to force every phone to be one you like? Immoral.
That's all it's about. Not a difference in definitions or confusing on his part, he's just saying you've got morality all wrong and need to reconsider your position.
For a society to function there needs to be balance. ‘You can do whatever you want as long as enough people pay you to cover your bills’ gets bleak fast.
It's a net benefit for society, even if you don't personally like it.
