NPR is quitting Twitter, saying that the social network owned and run by Elon Musk is "undermining our credibility." The decision was made about a week after Musk branded NPR with the "state-affiliated media" tag, which is typically applied to propaganda outlets controlled by governments.

"NPR's organizational accounts will no longer be active on Twitter because the platform is taking actions that undermine our credibility by falsely implying that we are not editorially independent," NPR said in a statement provided to Ars today. "We are not putting our journalism on platforms that have demonstrated an interest in undermining our credibility and the public's understanding of our editorial independence."
