I'm not complaining about anything. I'm pointing out that there are a lot of assumptions in that statement. Without them, there is not much of a statement at all. We don't know the margin of profit on any of these cameras. They could be selling them at a loss to make it up on lenses. There could be a huge profit on one of them and a very small one on the others. There could be any number of factors involved. If you have actual data for that, great.
There's less assumption in that than in the raw addition of the price of the cameras with no weighting for sales volume, but you aren't arguing with that post. I wonder why.
