EDIT: Enshittification, also known as platform decay, is a process in which two-sided online products and services decline in quality over time. Initially, vendors create high-quality offerings to attract users, then they degrade those offerings to better serve business customers, and finally degrade their services to both users and business customers to maximize short-term profits for shareholders.
It peaked right before cloud and streaming became a thing. Since then, we as consumers lost control of it, and the big tech is since then doing what it wants with it.
