Thank you for taking the time to communicate with us on this issue, and sorry for replying to this rather late.
The way I see it, the game page descriptions consist of what the publishers / developers want to say about the game, but GOG's claim is to be a curated store, and recent CDP statements say that this will be emphasized more now, so the purpose of the release article is to say why that game is on GOG from GOG's perspective, what made it successfully go through the curation process.
That was what the old release posts did, with lengthier descriptions that sometimes went beyond the game itself, maybe touching on the impact it had in case of older games, or something about how it was made or the developer, or influences and inspiration etc. And, of course, that was already gone when the descriptions basically became one-liners, and that was when it became a problem from my point of view, but I guess it took this extra step for a critical mass of users to be bothered as well in order for the outcry to make itself truly noticed.
There was also that promise made to developers in the past, that because it's a curated and smaller store, GOG offers each game its time in the spotlight. But that was also largely gone when the redesign hit and news were relegated to the bottom and made to scroll off so quickly, so in case of more releases people may well never see some articles even if they visit frequently and know to look all the way to the bottom.
So, from my point of view as a user, release posts have a purpose if they actually tell me something, preferably from GOG's perspective, past what the dev/pub put in the game page description. Without that, might as well do away with separate release posts and just make a single one for each day, just listing that date's releases, whether one or dozens. That should also make it so posts don't vanish from the front page altogether so quickly. (Not that I in any way advocate that approach, mind you, two wrongs don't make a right, but it would be less bad than this I'd say.)
On a related note, however, the sort by date added option really must return to the catalog. And assuming that the date is stored somewhere, it would be nice to even display it, and also perhaps add a way to filter/search according to it.
