Advertising in an SEO game. Get ranked in Google and take a few pennies from millions of drive-by users.

Subscriptions is a loyalty game. Convince users of your value and get them to commit to becoming a supporter for an extended period. Get them to install an app, accept breaking news alerts and lean on you as a trusted source.

Micropayments is neither. There's no obvious path to generate consistent micropayment revenue. Maybe for like long-form features, but not for daily newsrooms.
