They shouldn't subsidize it but they should at least sell it without profit.
The increase in price from 512GB to 2TB is more than what consumers would pay which shows they are profiting. It's even cheaper to get the 512GB version and buy a 2TB SSD yourself, plus you'd still have the 512GB drive for other things.
You misunderstood. No profit does not equal loss.
The employee builds a Steam Machine with either a €100 or €250 drive. All costs are the same except for that drive. However, the difference in price the end consumer pays is not a €150 difference but a €320 one.
This implies Valve takes their costs and just adds a percentage margin over it for profit. And I'm saying they shouldn't do that. Pay what must be paid and let us pay the same.
