At the time VVVVVV was added to the catalog, it had
418 votes in the community wishlist. That's 38 times more votes than Cooking Simulator had when it was added here. Just a reminder that eight years ago the audience of GOG was smaller than two years ago
(when Cooking Simulator received only 11 votes), and 418 is a pretty solid number of votes.
I also found a release announcement and even at that time no one was really interested or excited about this game:

Even I know about it and have played it, and I'm not a big fan of obscure indie games. To me it's like calling Hotline Miami or Super Meat Boy "very niche" games.
Oh, and there is no reason to compare finished projects with projects that are still in development. VVVVVV and especially Heroes III are projects that have been finished a long time ago, which means that all the updates and content have already been released when they were added to the catalog. Now they just make money for their owners. (:
Unlike the two above, Cooking Simulator is still in development
(it should receive a new content update on Steam soon). If you were a publisher / developer, would you like to spend your time and other resources supporting a version of the game that brings you almost no profit? You will probably say that you will definitely support this version of the game, no matter how much money it makes, but try to be honest.
fronzelneekburm: @topic: I hope those poor, unfortunate souls who got suckered into buying this thing will be offered refunds.
It would be nice if the money for these refunds was taken from the salaries of those curators who accept such games, knowing that the community is not really interested in these games. Maybe it will teach them a lesson, and they will finally start choosing games more carefully, listening to the opinion of the community, and stop rejecting games that are really in demand.
