The article didn't say that, no; the fact that the whole article is a criticism of Mozilla would seem to be an implication that that criticism would extend to Mozilla's argument, but that's an indirect implication, to be sure. But the trouble is that, if that wasn't the point of the article, then once again it seems like a rather silly topic for an article. If the author is really purely interested in people who criticize one company but not another for arbitrary reasons, well, I'm not sure I can see much that's very compelling in that.

To put it bluntly, if he's not actually talking about the software or freedom or the market or anything of substance - if he really is just saying Mozilla should either shut up or criticize Apple, without any regard to whether the criticism is right or the companies being criticized are wrong - then he is being petty, plain and simple.
