If a Bad Actor gets ransomware into my computer, how much I'll pay to get my files back (or stop them going public) is limited by how much money I have (ability to pay), and further by how important those files are to me (incentive to pay). Datafarming has built ransomware into our computing by convincing us to do it on their computers instead of ours.

Pricing for ethical services is further complicated by the fact they're often competing with a cash price of $0. So while they need to keep prices within people's ability to pay, if services set prices too low, they risk making prospective users sceptical about their financial sustainability, competence, or honesty.

"In situations where there is real competition, providers are usually forced to drop "pay as you go" schemes in response to user preference ..."

Shirky sums up his whole argument for why micropayments systems have failed every time in 3 words:
