It’s long been known that social-media platforms like Facebook, Twitter, and YouTube (owned by Google) delete significant amounts of user-posted content. Some of what gets removed is in clear violation of legitimate standards governing pornography and pirated content. But a lot of what gets pulled down is neither offensive nor illegal. Rather, it’s content whose message these platforms disagree with.
The practice has affected a lot of conservatives—like Milo Yiannopoulos, banned for life from Twitter—but is hardly limited to them.
