I think you're raising two points here? 1. NPR used to have a stricter separation between editorial content and news content. I agree and you're right I think this got a lot worse after 2016 across the board and IMO NPR has been better than many other agencies about it. 2. NPR took a turn left. I disagree. I think they continue to be vaguely American center-left and haven't really changed much. In general it's quite hard to define "left" as there's multiple groups, but yes since 2016 the social justice left has become a bigger part of the conversation.
