I'm also considering the transition in the Steam marketplace as a recent example. Their opening from curation started with Greenlight, a fast track program with some but minimal curation. There were a few turds but by and large the games that came through were of some general quality. Enter phase 2, Early Access. The minimal barriers were removed except "will it run", adult content allowed, and a smaller hosting fee used. And in came the parade of low effort hot garbage. Recommendations in their platform are hard to come by now. Random impulse buy while scrolling rarely happens for me now as discovery of actual good games for me is much lower and I feel like the platform as a whole has suffered for it. I could see a similar trajectory for the app store albeit with my value of the services being placed in different categories.
