They told him whoch changes they want him to make. He dances around it a lot with "surely I can't get consent from the whole Internet", but he did understand that they want him to use Safari.
I don't agree with Apple here, I think his app should be fine.
But that's what they said, and just because they did not pull the other apps yet (for all we know), doesn't mean he has a point asking about those.
And why not ? How else will we question arbitrary enforcement without pointing out to the instances of arbitrary enforcement ? Surely, he is not asking that they take down those other apps. He just wants to be in the same bucket as the others.
You don't discuss arbitrary enforcement with Apple's reviewer.
Either they enforce arbitrarily, or they don't. In neither case do they care about your opinion on it.
If you want to have that discussion, have it. On your blog. On Hacker News. On Medium. But not in the "please reinstate my app" conversation with Apple.
