This really does not sound healthy. The game is released, for a certain amount of money. If people don’t like what they get for their money, they simply should not buy it.
But by now gamers have been so trained to expect to endless content treadmills and all their ilk like mtx and battle passes that publishers/developers get egged on if they don’t work on their game 24/7 and forever.
Gamers are not asking devs to work until burnout on social media or forums, that’s management and usually in person or department/company policy and procedure.
Edit: more specifically to the article for solo devs they are talking about critics complaining they should have made something bigger which is not a bad problem to have for securing funding for future games if people like your art enough to request more and doesn’t require working burnout hours.
