Well, did you read the first two sentences of the article?
> Facebook boss Mark Zuckerberg says users will be able to turn off political adverts on the social network in the run-up to the 2020 US election. In a piece written for USA Today newspaper, he also says he hopes to help four million Americans sign up as new voters.
The USA Today article is easily located: https://www.usatoday.com/story/opinion/2020/06/17/facebook-v...
My conclusion is that Hacker News has a bias in favor of a news source like the BBC over a news source like USA Today which is strong enough to overcome USA Today having the original story yet have the BBC article be the one voted up.
