NPR.org decides to break all of its RSS feeds because of GDPR

If you subscribe to NPR RSS feeds like NPR News Now and request them from an IP geolocated generally in the EU area, you will no longer be served an RSS feed XML file, but a consent warning that assumes you are a human that can click through to the feed.

This is idiotic.

Luckily there is a workaround — add this to the end of the RSS feed URL:
&trackingChoice=true
