What usually happens, is that the game is added quite a while before it became available for sale on, say, gog.com. Abandonware used to be just that. There is a new trend to keep old games alive, though, and we support gog because they have the right to sell the games from the developers. Once a game is sold, it's no longer abandonware. We don't take the review down, however, but instead insert a buylink so its fans can find a working copy of the game that is also supported (and often patched or improved a little in terms of sound configuration) and runs well in DOSbox.
I hope that helps
And sorry if we've been a bit snippy with you
