Almost every country in the world has, in its constitution, a promise that its citizens enjoy freedom of expression. Almost every country also has laws that limit it. The interesting question is where, exactly, the line falls — and who gets to draw it. In the 21st century, that argument is being fought on four different battlefields at once.
The first battlefield is the newsroom. Journalists in dozens of countries are jailed every year for publishing what governments would prefer to hide. According to the Committee to Protect Journalists, more than 300 reporters were in prison at the start of 2024. Press freedom is under pressure not only from dictatorships, but from lawsuits, from social-media abuse, and from the simple collapse of the local newspaper.
The second battlefield is the platform. Facebook, YouTube, TikTok and X now take, every day, thousands of decisions about what a billion users can and cannot post. A joke, a protest video, a piece of medical advice: each one is either allowed, hidden, or deleted. These are, in effect, private companies acting as the world's biggest editors — but with almost no legal responsibility to anyone.
The third battlefield is the campus. Universities have always been places for uncomfortable ideas. Recently, some students and staff have argued that certain speakers should not be invited at all, because their views cause harm. Others reply that the answer to bad speech is better speech, not silence. Neither side is entirely wrong, and neither side is entirely right.
The fourth, and newest, battlefield is the algorithm. What you see online is not chosen by you; it is chosen by a piece of software that has learned exactly what will keep you scrolling. If it turns out that anger and outrage keep people scrolling best of all, then anger and outrage are what the algorithm will feed you — and neither the law nor free-speech theory has really caught up with this yet.
