A. I'm not ommitting it. It still suggests that there would a benefit of using a TB4 cable. There isn't.
B. The product is very useful if you want to connect something with actual thunderbolt 4 capabilites. Like laptop to a docking station. It's just that in the case using the higher-standard cable doesn't add anything overusing a cheaper one.
C. If you just care about charging, you can get a offical apple cable for $20. They don't sell USB 3.2 cables from what I can see in their shop. So bascially if you want to use the new IPhones max transfer speed (which is just double what what you can do with the cheap one) they force you to buy a cable that is 10x more capable and costs 4x as much.
But you can could get a cable that can utilise the full capacity for around $10 bucks from Samsung or other major brands.
