That's probably largely true of 5th Edition. It's a focus group led, neutered, milquetoast version of Dungeons & Dragons. All of it's official product releases are whittled down to the least possibly offensive common denominator. And the D&D Beyond software is clearly a first attempt at an Apple App Store style walled garden from which to extract rent forever and ever.
But the auteur creators aren't gone and creativity hasn't been killed. From Patrick Stuart's (the writer, not the actor) projects like Silent Titans[1] to the bizarrely delightful Mörk Borg[2] to Luka Rejec's Ultraviolet Grasslands[3] to the space horror game Mothership[4]...
There's an insane amount of creativity in the design of tabletop roleplaying games today, and I haven't even moved that far from D&D-alike gameplay.
What's more, these auteurs are making good money without optimizing for maximum money as if they were MBAs with a drug habit to support or SV startups with "angel" investors demanding an insane return. Look up the Kickstarters for any of those projects in the paragraph above.
Even for a Jacobin piece, this article is extremely myopic, poorly researched, and comically fatalistic.
