What shady crap? They built a desktop monitor controller that allowed variable refresh, they sold it to people. Over a year later and AMD have worked with some other companies to allow them to do the same, they are also going to be charging money for these new monitors.
That is what companies do, they make a thing and they sell a thing, what price people are willing to pay is down to the people doing the buying.
I havent lost my mind at all mate, your saying things that dont make any logical sense. You are literally having a go at nvidia for making a product and putting it up for sale. That is what all companies do, make things and try to sell them.
