This looks like a good idea on the surface but there is one factor which is easy to forget but still very important. If you have a subscription with a news site instead of paying for articles individually you might not read articles you would have read otherwise. I often find myself enjoying articles much more than I would have anticipated just considering the title. If a per-article business model will become the norm the clickbait-problem will undoubtedly get worse. Deeper and less catchy articles will fade from media outlets which hurts the industry as a whole.

That's one of the benefits of streaming services in the music industry. Nowadays it's much easier to discover artists which deviate from the mainstream because you don't have to spend any extra money to discover a new artist. I think this is healthy for the music scene and I suspect the same is true for journalism.

Also if you have a subscription you are probably going to read more articles than if you would have to purchase every article individually even if it's less expensive to do so. People reading less is hardly a desireable goal.
