(CBS DFW) Social media bans of conspiracy theorist Alex Jones have thrust Facebook, YouTube, Twitter and others into a role they never wanted — as gatekeepers of discourse on their platforms, deciding what should and shouldn’t be allowed and often angering almost everyone in the process. Jones, a right-wing provocateur, suddenly found himself banned from most major social platforms this week, after years in which he was free to use them to promulgate a variety of false claims.

Twitter, which one of its executives once called the “free speech wing of the free speech party,” remains a lonely holdout on Jones. The resulting backlash suggests that no matter what the tech companies do, “there is no way they can please everyone,” as Scott Shackelford, a business law and ethics professor at Indiana University, observed.
