Well, I am not the IAP nor the original comment author. But as far as I understand the rules, every comparative advertisement, that is saying competitor X is bad instead of our product Y is good, has the same problem: X can easily say that the selected feature is just one random pick of a range of features. They may retaliate with some other fact. That may also be factual true, let’s say, BYD cars are build without union oversight.
And that starts a negative cycle. You can be in favour of that. It might be entertaining. But by the book that is not allowed to keep advertisement a little more civilized.
Whilst I’m not defending any advertisement at all, one can easily see what happens when it is allowed to talk about your enemies instead of what you provide. Just look at the logical end of this in form of the attack ads of the US political campaigns.

True. But BYD is also a very, very large corporation.
