Trying to convince somebody they want to buy something by bombarding them with ads on every web page is shitty. I don't want to be exposed to it. I don't want my kids exposed to it.
Then to build your content business on top of the shitty advertising industry that seems kind of a bad idea.
I think if people want your content they will pay. Publishers just need to bundle it the right way.
And I've said it a few times here on HN, but if we as a society think news and current affairs is important, we shouldn't trust it to commercial organisations driven by profit, we need independent, publicly funded news like Australia's ABC.
