Two thoughts. 1) The 80/20 rule is a percent so absolute numbers can go up while relative numbers stay the same. So I’m not sure looking at absolute numbers of available items over time is good enough. You’d also want to look at sales/access I think (which isn’t the easiest to do). 2) You do bring up a good point. I wonder if there is a difference when an individual entity is largely responsible for market costs vs a market of producers where many individual entities are responsible for the costs / risks. I haven’t thought this fully through but it seems like there might be something there (amazon products vs amazon seller products, spotify may be an exception here but how much music isn’t on the platform? vs soundcloud, youtube handles streaming costs/sales in the form of ads while producers handle production costs, and podcasts are almost entirely paid by producers unless on spotify where streaming costs/sales are paid by the platform)
