The comment I was replying to asked for one example and asked specifically about persistence, that's why I gave the example of something I remembered reading 7 years ago (the work itself is 8 or so years older than that IIRC).
> How about you enumerate all the digital content you've used over the last week (books, music, movies, games, software, tools, etc) and identify what percentage of them were created with zero expectation of financial gain? Yes, some people make digital content as a hobby and produce laudable results, but most of the time if you want quality you're going to have to pay for it because "zero distribution cost" doesn't put food on the table.
That's the wrong percentage to ask about - a better question is how much content would have to disappear before it started to noticeably impact my life. 99%? 99.9%? 99.99%? That would still leave many lifetimes' worth of high-quality content. Are you so sure those hobbyists couldn't sustain the 0.01% or less that people need?
