When people learn how these stations are actually funded, they change their tune.
Unfortunately the drumbeat of "Defund NPR" etc. has been very loud for decades and particularly loud (and misleading) lately. To hear some folks tell it, PBS and NPR are giant sinks where billions of taxpayer dollars go to fund overpaid executives, "woke" programming, DEI programs from Sesame Street to Antiques Roadshow, and "radical" shows like This American Life. Truth is, the educational content is worthwhile, the news (both on TV and radio) is pretty balanced (and doesn't constantly shout opinions at you) and as a public service and use of the public airwaves, it's a pretty good deal for a relative pittance of federal money.
Pulling the funding (which facilitates the donations getting to the stations) will not magically balance the federal budget. It's equivalent to a rounding error.
