its not about the whole
"its still a good card"
Its about false advertisement, heck if you bought a device that said, it poops out gold, but instead it only pooped out silver, it'd still be pretty amazing, it just wouldn't be the thing you bought.
Like i said before, if they get away with this, expect even worse things in the future, all hidden away behind a nice wall of "BUT ITS STILL GOOD".
