Families of Buffalo Massacre Victims Sue Meta, Reddit, and Google Over Conspiracy Theories

From the article:

“By his own admission, Gendron, a vulnerable teenager, was not racist until he became addicted to social media apps and was lured, unsuspectingly, into a psychological vortex by defective social media applications designed, marketed, and pushed out by Social Media Defendants, and fed a steady stream of racist and white supremacist propaganda and falsehoods by some of those same Defendants’ products,” the lawsuit reads.

I'd say it is at least partially social media's fault.
