The obvious response to this is malicious compliance. OK, every week or every day NPR tweets something to the effect of "to get the latest NPR news, go to [URL]" where URL is a page on NPR's site with its preferred social media outlets. No news. No updates. Nothing that would help engagement on Twitter, but the account is active. It tweets. Of course, Musk will try to force them to engage with Twitter as if it's business as usual and try to invent some other reason to either reap the account if they don't comply.
