If they're claiming it's sapphire, and there's no sapphire in it, and it scratches just as easily as regular glass, that's called "false advertising".
No sapphire in it? Did you watch the video? The show it's 85% Aluminum oxide (sapphire) with a very thin layer of niobium on the interior to improve the refractive index. What the issue is here is the carbon impurities in the sapphire, not that there is no sapphire.
