They're discontinuing the Facebook Like button on third-party sites. That's pretty wild! The Like button used to be Facebook's major initiative back in 2010. https://en.wikipedia.org/wiki/Facebook_like_button

Media sites in particular used to try to drive people to click the Like button, causing their articles to appear prominently on Facebook. And since it was an <iframe> running on every site, Facebook would automatically know what articles you viewed, data that they could use to target ads to you.

How/why did that die out, I wonder?
