How is GOG a viable business if everything gets pirated?

This is a really old question and a really old solution.

It turns out that piracy is actually a service problem. Services like Steam and GOG provide a decent enough service that piracy becomes less common.

Many games on GOG are at the tail end of their sales cycle (i.e. were released on Steam long ago) trying to eke out a few more sales, are from small indies for whom any attention at all is good attention, or are very old^H^H^Hclassic games that garner purchases for nostalgia's sake by older gamers that can afford more discretionary spending.
