Because since 2010 Google has started to include social signals as a consideration to assess whether a website is worthy or not on the front page of Google, even though at that time it was not 100% implemented in Google’s algorithm, but now it is guaranteed to have been implemented.

Google wants their first page to be filled by websites
with quality content where the benchmark is that the content provides benefits for the readers, to find out whether the content is useful or not, it seems that Google experts take the logic that if a lot of content is shared by users on social media then the content is useful content.
