Search for "Public Radio Station Revenues (FY20)" and you can plainly see a graph that states that 8% of their money comes from "Federal appropriation via CPB" and then another 5% comes from a combination of Federal, state, and local government sources.
The minute they get slapped with a state funded label they pretend that they only get 1% of their money from the government, in contrast to their reported finances for the past several decades. It is weasel word behavior to pretend that 8% of entirely federally sourced funds is irrelevant because it is passed through the CPB first (which is itself a state media agency, created by Congress in the Public Broadcasting Act of 1967)
