I mean its not really a cost to anyone. Bandwidth is paid for by Valve, games can be deleted locally, etc.
I'm already disillusioned and basically done with these devs anyways. They've consistently gone the wrong direction over time. The game's golden age is far behind us, as far as I'm concerned.
If a user only installs 10 games the required storage space would go from 1.5TB to only 250GB.
Currently a 250GB SSD costs 300$, 2TB is +1300$....
