Heavily biased article. There are just as many studies linking it as there are unlinking it. I'm not saying it does cause depression, but I am heavily disputing the claim that it doesn't. This was the most balanced article I could find on the subject: https://www.hsph.harvard.edu/news/features/is-social-media-use-bad-for-young-peoples-mental-health-its-complicated/
Though I do agree with op that anecdotally the state of the world probably plays a bigger role.
