https://en.wikipedia.org/wiki/NPR#Funding> "According to CPB, in 2009 11.3% of the aggregate revenues of all public radio broadcasting stations were funded from federal sources, principally through CPB; in 2012 10.9% of the revenues for Public Radio came from federal sources."
It appears approximately 10% of NPR funding is from the US government. That's a decent chunk, but not enough to hold sway if it goes against the majority of their donors.
Contrast that with a services like the BBC and RT which are almost all funded by taxpayer money:
https://en.wikipedia.org/wiki/BBC#Finances
> "According to the BBC's 2013/14 Annual Report, its total income was £5 billion (£5.066 billion),[2] which can be broken down as follows:
* £3.726 billion in licence fees collected from householders;
* £1.023 billion from the BBC's commercial businesses;
* £244.6 million from government grants, of which £238.5 million is from the Foreign and Commonwealth Office for the BBC World Service;
* £72.1 million from other income, such as rental collections and royalties from overseas broadcasts of programming.

"When it was established in 2005, ANO TV-Novosti invested $30 million in start-up costs to establish RT,[14] with a budget of $30 million for its first year of operation. Half of the network's budget came from the Russian government; the other half came from pro-Kremlin commercial banks at the government's request."
"About 80 percent of RT's costs are incurred outside Russia, paying partner networks around $260 million for the distribution of its channels in 2014."
"In 2015, RT was expected to receive 19 billion rubles ($307 million) from the Russian government in 2016."
