Enshittification, also called crapification and platform decay, describes how two-sided online products, services and platforms worsen over time. First, they attract users with a quality service. Then, they reduce quality to better serve business customers. Finally, they degrade the service for everyone to maximise short-term profits for shareholders. This term was coined by writer Cory Doctorow to explain the decline of platforms like Amazon, Facebook, and Twitter.
