Honestly, I'd ask the developer first about it on such a subject and such a scenario, and listen to them. For example, if they say "You can give the copy to a few people at _____.", then I don't see the problem with it.
Otherwise, I wouldn't really re-upload it, in my opinion, as the developers probably have their reasons for taking it down (even if they're personal ones).
I understand alternative views. Some see a game as a work of art, and think art must be preserved. But, I think the comparison can still get a little muddy past surface level, so I'd still ask the developer.
