Can games donated to DiGA still be distributed on a commercial basis?
Well, why not? The donators remain the owners of the legal title. It is his turn to determine the conditions of making his program available. And this allows for a wide range of possibilities spanning from use restricted to private and scientific purposes to the publication of the source codes. Depending on the owner’s decision he can carry on to use his game commercially even if it can be expected that the value of the license is decreasing after he made the game available. This loss however is outweighed by the simultaneous gains: a place in our venerable “Hall of Fame” and to be relieved from the burden to be the only one bothered with the question of preservation.
