So a commenter on HN quotes a commenter on Reddit who said that some commenters on BackReaction 'explained to her she was wrong'.
That's grand and all, but is anyone in that chain actually a cosmologist like Sabine Hossenfelder?

Wrong about what, exactly? The details matter here! It seems the commenters point out that she's wrong that it's difficult to explain with particle dark matter, but if there's anything there to show that she's wrong about it being explainable with STVG I've missed it.
