If you implement subscriptions + micropayments but let all the web scrapers through that’s not a sound new attempt at a system. That’s the same leaky system with micropayments slapped on top. See?
Ancestor comment https://news.ycombinator.com/item?id=45302115 already starts with the context of not wanting to subscribe to a random site, so I don't know how we don't end back up exactly there to have a non-leaky system with micropayments on top?
But the solution to not wanting to subscribe is to pay the $0.50 or leave. Before it was: find a way around paywall or leave. The OP maybe wants free things only?
This sounds like no true Scotsman.
I guess it's tautological that nobody's tried the right model because nobody's been successful.
