This needs "(2014)" added to the title.

This appears to be a repost of the famous Facebook study that manipulated people's news feeds: https://www.theatlantic.com/technology/archive/2014/06/every...

I agree. Although perhaps more infamous than famous.

Thanks, I thought this was new, and was kind of amazed that they were doing this again.

An important point about this result: the significance is high because they had a huge population to test on, but the effect size is very small. The effect size is 0.001 which means that if one of your friends posts something negative (or positive), you have a 1/1000 chance of also posting something negative (or positive) as a result that you wouldn't otherwise have posted.
