I tried looking into why would they call the "shaken baby syndrome" "junk science", since it's a very real thing accepted by all the reliable sources I could google. I had to read into their linked sources to understand what part exactly is "junk".
So just to clarify, it's not that the "shaken baby syndrome" isn't real. It is. The "junk" is the part in which scientists identified three symptoms ("bleeding between the tissue layers covering the brain, swelling on the brain, and bleeding at the back of the eyes") that happen from shaken baby syndrome, and some forensic practitioners read that as a bi-directionally exclusive relationship: if the three symptoms occur, it must be shaken baby syndrome. There isn't enough evidence to support that other issues couldn't cause the same symptoms, and using that triad as proof of abuse is controversial.
But shaken baby syndrome is very real, and it causes those three symptoms. The wording of this article (including the subheading) repeatedly seems to imply otherwise, which spreads dangerous misinformation that reads as "shaken baby syndrome is a myth" and that "physically abusing children doesn't cause shaken baby syndrome". That is "junk journalism".
Gamergate was one of the first online instances that showed how easy it is to spread lies and misinformation through social media in order to manufacture outrage and weaponize it against specific targets.
The same exact tactics have been used by the far-right since. Gamergate felt like a testing chamber, before the full blown nazi propaganda plan that's getting far-right politicians elected in many places. I live in one of such places, and the online tactics used by literal nazis against progressive politicians are 1-to-1 the same used in gamergate.
Those issues with social media have never been dealt with. If anything, social media has become more mainstream since, and now these tactics of lying and manufacturing outrage have become more powerful.
Traditional media seemed to have some semblance of accountability (although not really), but in social media, anyone makes up shit, people will take their word for it, if they like what they hear (or aligns with their beliefs), and it doesn't matter if it's debunked, because no one listens to that part.
The only solution is, and has always been, a zero tolerance policy against any kind of hateful or bigoted behaviour, by the people who control these online spaces. No one expects 4chan to moderate their content at this point, but when someone makes a new online space for conversations, those same people shouldn't be welcomed, or they'll shit all over the floor, turn it into another gross place, and you'll have to start over.
These new complaints about "wokeness" in games, that happen with every game announcement, aren't even dog-whistles at this point. They've been straight up howling for a while. The follow-up attacks, threats, lies, the dismissal that "none of this happens, it's all made up", and the support of fellow misogynists (like the companies with a history of sexism mentioned in the article), are all just part of the program.
And of course, you can see them in some of the comments in this very thread.
