Because not all government funding is federal funding.

Random example from an NPR member station's web site:

  KCRW is supported, in part, by the Los Angeles County Board of Supervisors through the Los Angeles County Department of Arts & Culture. The Department's Organizational Grant Program helps fund a wide variety of arts, culture, and music programs that you hear on air each day!

I apologize for my imprecise language. The 13% I quoted includes "Federal, state and local governments". Again this is all on the web page we're all discussing, in a very easy-to-understand chart.

You're assuming Rahim Nathwani is not purposefully feigning ignorance / misunderstanding. He's 100% doing it on purpose.

The question is: why is he dying on this hill?

NPR has a history of downplaying their government funding, I'm not sure if you should use them as your main source. I know in the past they've said it was around 5%, while independent investigations found it was closer to 20-40%

That's the source we're discussing here. If you have some evidence that they're lying about this then please post it, I would genuinely be interested to see it.

Thank you for the number. In context, the EU is 15% of revenue for most ad based tech platforms, and its regulation has shown unbounded control over them.
