Last week, Facebook made its first concession to Singapore’s fake news law by denoting a post that the government said contained false information. However, with other regimes around the world grappling with the problem of how content is regulated online, there’s a chance that the platform may have opened a door that it will be unable to ever fully close again.

According to the BBC, the post in question was from the news site States Times Review, which was updated with this note from Facebook following a complaint from the Singapore government: “[Facebook] is legally required to tell you that the Singapore government says this post has false information.”
