Hossenfelder is just a cynic that critizises more or less everything that isn't her own work. She even tried to discredit LIGO a few years ago - not even using her own insight but merely by paraphrasing what a Danish group thought they had seen as error. This issue has been resolved since then and the Danes just misunderstood parts of the original paper.
Lol. These conspiracy scientist outgrowths are getting truly insane. "Lets ignore all these published, peer reviewed independent studies that confirm the discovery and listen to one random guy who's most likely not even a physicist and writes his ideas on wikipedia."
