Caesar.: The concept of abandonware was born when it seemed that none of those games would ever be available again. But now, with digital distribution, it's harder to place the line.

I think some abandonware sites have started to link to GOG when a game can be bought here. That's great, when the game is sold. But if it's completely impossible to buy a certain game, then I don't see it as morally wrong. If I were a game developer, I'd prefer people to be able to keep playing and ejoying my game.
