They've been making a killing with this. Even when I recommend AMD friends/family members still get Nvidia. Unless I'm at the store or placing the order, my suggestion for a GPU often goes unheard. Which, sort of annoys me.
I was at Microcenter and have first hand experience with sales clerks underselling AMD cards.
End of the day, NV's market brand/presence is huge, and these forums ain't going to do much to change that. Just cruising other forums that get 10-100x more this places traffic, NV is cemented as the go-to for PC Gaming.
NV knows this. And they are milking every single dime they can in the process.
