The dev (one person) making the small effort once, or every player interested in his game having to go dig for updates, one after another? I think it's easy to agree on who should be required to make the effort in these cases, the one whose effort makes the information instantly available to everyone else. Why should players have to join dedicated Discords to get updates? One could even argue funelling people towards Patreon by only giving updates there while abandoning the game page is a dishonest way to go about increasing revenue.
