Oh I don't think they imply they will cover the costs. More like the only ones to know exactly the installs will be them, Microsoft, Sony, Nintendo , and that's why is done this way. Also to simplify the billing as well they already pay them for putting the game in their respective stores in one way or another.

Of course they could put a remote call that notified back to them in the game engine... and probably will work this way for PC, but probably the console companies might not be too happy about it.
