IIRC, it’s in the article, but what makes enshitification so prevalent in tech is that it mostly involves networks, wherein part of the value of using the application comes from the presence and concentration of other users and providers on it (network effect). Even Amazon, Netflix, and Uber, are subject to that effect because they capture providers, not just users you will interact with. It’s a somewhat uniq trait that really exacerbates the problem. This trend will probably continue untill interoperability is legislated.
