Germany has (used to have? I don't follow this closely) the "church tax": citizens are obligated to pay the tax no matter how much faith they have, but are free to channel it to a denomination/organization they believe in.
Maybe a liberal, democratic state could successfully build something similar for news organizations: all citizens have to pay a "journalism tax", which they then channel to a subscription for a vehicle they trust.
Yes, a million ways this can be abused, the government may censor opposition, etc. I know, I said the idea wasn't great. But worth pondering. Also, this is based on a very stylized understanding of how said German tax works (I'm not German and never looked at it that deeply)
btw I understand this is the opposite of "free", but more about journalism financing in general.
