I tend to agree, but I also really like what YouTube has created with the ability to monetise videos: Many thousands of people who are now full-time independent publishers. From the demos that I've seen of this game, it could give aspiring game makers a pathway in the game industry which doesn't require joining a big studio, or learning (relatively speaking) complex tools. But that only works if they're able to sell their creations.
Perhaps if they have strong content moderation (to prevent spammy stuff which tends to occur when money starts getting involved), then they might be able to maintain a great community while creating more independent developers.
After all, Roblox has shown that monetisation in the game-creation space isn't necessarily a disaster.
