A sliding-scale subscription model would be nice, where I could say "I'll pay $100 per month and have no adverts at all" or "I'll only $5 per month, and I'm happy to have a lot of adverts".

But the advertisers probably want access to the kind of people who are prepared to part with a lot of money to avoid advertising. You see this in the FT and Economist where it's more expensive to advertise to subscribers, because the advertisers know those people have higher disposable income. If all they can have access to is lower-paid people, I guess there’s a risk a lot of the advertisers will not bother.

Maybe there's just an inherent problem here. News can be good quality, independent from government, free from advertising, and available to all. But it can't be all of those things at the same time at a national level.
