It matters because it points towards a common failure mode which we've seen repeatedly in the past. In the 1990s, people routinely published news articles like the OP (e.g. https://www.nytimes.com/1999/04/26/business/technology-digit...) about how researchers "knew" that violent video games were causing harm and the dastardly companies producing them ignored the evidence. In the 1980s, those same articles (https://www.nytimes.com/1983/07/31/arts/tv-view-the-networks...) were published about television: why won't the networks acknowledge the plain, obvious fact that showing violence on TV makes violence more acceptable in real life?

Is the evidence better this time, and the argument for corporate misconduct more ironclad? Maybe, I guess, but I'm skeptical.
