I've made a start-up that has really tried making micropayments work (blink.net) and I know there have been many other attempts.

Some of the pain points can always be addressed, as it's just implementation difficulty (having an auto-pay system when opening and article, and actually being able to get a refund within a short time window if the title was clickbait -- with some limitations of course).

The main problems that always remained were:

- the dificutly in convincing a user to actually pay, which was a psichological barrier. People also don't understand that many articles would have to be priced at 20-50 cents, even more, to be worth it, or there should be an issue pass with the actual price of the whole issue.

- the publishing industry being a mess, hard to coordinate as everyone wants to do their own thing, and early experiments failing, ruining the reputation of the idea itself. Many people say micropayments are something that needs a good time, but nobody knows when that time will come.

- the huge fees that processors take (2% + 29 cents), meaning we needed to load into a wallet a minimum of 5$. After learning all the tricks of the industry, I felt a need to throw rotten tomatoes at whoever thinks that cashback should be legal.

The combination always made it a horrible problem, and at this point I'm even considering making the existing project a non-profit, if that might get something off the ground, but now it's just in low-maintenance mode.
