I imagine steam survey has a long tail of old systems. I wonder what the average RAM capacity and other specs for computers from the past year, 3 years, etc.
I think that is how collections work. When a business can't get you to pay they sell the right to collect it to another "collections" business (let's call it Y). Y pays a fraction of the amount owed for the right so even if they can get you to pay like 25%, they are still making a profit.
