The two examples I provided (Pepsi vs Coke & Mac vs PC) are evidence to the contrary. The comparison can be implied or explicit.
In the case of AMD, they are suggesting that they are bringing VR at a lower price than their competition.
In the case of Apple vs PC, Apple claimed it was bringing a cooler product.
In the case of Pepsi vs Coke, Pepsi claimed that it was a younger and cooler alternative.
Did you view that entire video?
Look at 4:02, policy statement from the FTC.
I suggest you look up what is subjective adverting vs objective adverting and then try to fit that in with comparative adverting, then you will understand what the differences are.
In the case of AMD, bringing VR to the masses, was BS, Polaris sucks at VR comparing to the 1060, have you been looking at the [H] Vr reviews for the past year?
It was hype and it backfired.
Apple vs. PC, Apple had better build quality then any other pc on the market, and the looks to boot, those two facts are subject and that is subjective marketing, but it was pretty much undeniable.
Pepsi is also a subjective adverting as well, yeah kids tend to go to pepsi because its sweeter and there is data backing that up too. or was, just looking that up, looks like its changed now as Soda has really dropped in sales.
