Buying "for Parts" but the parts are broken.....

I bought broken, snapped in half meta glasses for the internal parts like battery but they were completely dead. Like the battery wasn't even working. No worries as I just used it for glasses.

Then I bought a broken iphone, shattered front and back for parts to use internal parts. Then it seems the internal parts are broken. So why sell it for parts for technicians, etc?

Is this a "item not described" or just buying eWaste?
