I take a very large grain of salt if a researcher is literally based in California and they produce "findings" in support of a California-based megacorp such as Facebook. And then the headline is "lacks evidence" and "pose risks".

No shit sherlock, it lacks evidence because Facebook gatekeeps all the scientifically interesting data and they also don't share their findings from internal studies and human trials where they psychologically manipulatated minors.

There is a reason social media apps spam you with notification popups if you have not been active for the last 23 hours. They employ every trick in the book to keep you hooked and monetize your attention.

It is clear scientific misconduct by people working for Facebook who do numerous human trials on minors in order to increase their metrics and monetization. The fact they have crossed this red line should stop the discussion for every credible researcher in that field, because human trials on minors without consent are not ethical and there is no excuse for such behavior.
