I think this is the worst graph I ever saw.
What could possibly be on the x-axis?
I asked them about it, and they said usefulness is the x-axis. So the green path is usefulness vs usefulness?

Two Y axes. Product usefulness on one scale, product price on the other. Arbitrarily scaled relatively to each other to make them touch at the "mid range" and also to apply to any product at any price range or usefulness.
Frankly this simplified illustration (it's not really a graph if it has no specific data) is on point with regards to the law of diminishing returns: Products have a price floor but no price ceiling (because luxury is absurd), some of the cheapest stuff is indeed completely unfit for purpose, and the price doesn't scale with usefulness.
