A reported decision by Delta Air Lines to block "inappropriate" Web sites from its planned in-flight Wi-Fi service could be just the tip of the iceberg for airlines' control of Internet use..."It's so easy, once that precedent is set, to broaden ... the kind of information blocks that might be imposed," Rotenberg said. Considering how many of the world's airlines are owned by national governments, it wouldn't be surprising to see them filter out, for example, any site that criticizes the country's leader, he said.
