Twitter Controversy

Controversy is building over Twitter's decision to drop the account of a journalist who heavily criticized NBC, a move that was reportedly initiated by Twitter, not NBC. Jeff Jarvis sees this as a business ethics issue. The journalist, Guy Adams, says he's still awaiting an explanation from Twitter. Update: Adams is back on Twitter, as NBC lifted its complaint and Twitter's blog explains the situation. Kashmir Hill says NBC is the loser here. James Poniewozik reacts.
