I mean you are right, but on top of that I would not have trusted google to keep that service going. Generally I guess it is very unwise to trust any streaming service to keep going indefinitely, because there will always come a point where some old game is more work to support than it is worth.

If we gave some gamer the funds to run the gaming equivalent of archive.org I might have more trust in the service. Earning money and archiving cultural goods for future generations are not easily compatible goals.
