Who said that GMG are selling them at a loss?
Sure, their margin is probably tiny, it's conceivable that they are selling the copies at cost to piss off CDPR, but I doubt they are selling it at a loss. They probably bought bulk retail copies at wholesale prices just like any other re-seller such as BT games, Takealot, Amazon etc.
It probably is just sour grapes, but I wouldn't be surprised if this contravenes the conditions of someone's distribution deal.
