Busting somebody's balls because they're not abstracting away something as significant as 27% seems unreasonable. It shouldn't surprise you that somebody who dislikes giving 30% to apple would be proportionally less concerned about giving 3% to Visa.
It's hardly unreasonable; if their problem is, as they've said, "giving money to Apple", then it's not the amount, but the fact that Apple gets a cut at all.
And none of this is surprising, merely inconsistently applied logic. I fully understand what is happening here, clarifying statements will not help.
