ShadowAngel.207: (...) In this day and age something like gog wouldn't simply vanish because of bankruptcy like some small-time brick & mortar store. (...)
ciemnogrodzianin: OK, you're generally right. But do not confuse GOG with CD Projekt RED. They are the same group, indeed, but I don't think that anyone would ever decide to spend profits made on development just to keep GOG alive. GOG need to work for himself and it's correct what I've said - storage and support will be provided as long as new sales are fine.
GOG is not like any other store. In case of store you pay, take your product and go away. In case of services you're receiving some service as long as you pay.
GOG is different. You can buy 1000 games (yay, great customer, aren't you?) today and decide to download them every single day for the next century without paying a cent to GOG. In such case at some point they will get a loss from you as a customer.
Any business have ongoing expenses that they account for, and GOG is no different in that case. Rent for bandwidth and storage space from the provider(s) they use is something that they have already accounted for, and that provider's business
is to provide
storage and bandwidth (to simplify it a bit).
I don't know which CDN GOG uses for their game downloads, but regardless of whether it's Akamai, Amazon CloudFront, Cloudflare, or any other of several dozens, that's practically no more than a rent GOG pays for the service of hosting the downloads.
One or a rare few customers trying to do what you say will likely not even measure in the statistics for said providers considering the amounts of traffic they already serve.
