You only mentioned what buyers are choosing. That's completely separate from these media outlets are saying. What a specific demographic of media outlets are saying would not have a direct correlation on what buyers decide.
You removed part of the post that you quoted which referenced HUB. This is 100% related to what media outlets are claiming and evaluating how that holds up against the reality on the ground. Those outlets are claiming that large swaths of gamers are suffering due to 8GB and have provided no proof to that effect. The proof that we have points to lots of 8GB cards still being sold. Don't get me wrong, I'm not a fan of 8GB cards and I'm not advocating for their continued presence in the market. But the arguments being put forward by the talking heads on youtube are simply inane and clickbaity.
Also again I have to state that absolute terms like that are more applicable the more actual consumer choice there is. Even if we want to assume incorrectly that a 4060 and 7600 XT are otherwise interchangeable aside from VRAM the vast majority of buyers when they actually go to purchase something like this do not go to a store (or estore) and just see those 2 options immediately on the shelf next to each other with official MSRP pricing.
If 8GB provided a horrendous experience we would see significantly more uptake of competing solutions with more VRAM. To believe otherwise requires one to believe that consumers willingly pay money to suffer.
System memory (RAM) in the PC DIY market is priced like a commodity, it doesn't mean you aren't paying more for more RAM but you are effectively paying only a slight margin on top of the input costs. There's minimal additional pricing strategy and considerations involved beyond that. System memory for AIO type devices especially with soldered memory (think laptops, Apple products, etc) is priced like a luxury, the price difference can be well beyond input costs due to significant other considerations.
That difference isn't due to commodity vs luxury. It's due to the fact soldered memory solutions aren't upgradeable and have no competition and therefore have more pricing power.
