I'm not going to defend capital's ability to ruin things, but this is framing is not helpful. Enshittification as it was described by Cory Doctorow, who invented the term, requires two additional things:
1. A platform that tries to attract both producers and consumers. Amazon is the canonical example. The platform does what it can to attract enough consumers that producers have to use the platform to reach them. Then it squeezes out the value to the producers (e.g., hiking acquisition fees, etc.; competing with them and underselling them with cheaper alternatives). The final step is to destroy the value to the consumer, by degrading quality and increasing price. By this time, neither producers nor consumers have many levers to fight back.
2. Non-physical pricing levers. Enshittification requires the ability to observe consumer behavior and jigger pricing at great speed. We see this in Amazon again; ridesharing apps introduced surge pricing; ads are priced according to what platforms know about you. In a physical store, the logistical cost of changing the price of goods is nontrivial, so we don't see the same sort of gaming there.
Enshittification is a novel and illuminating concept, so we need to be careful not to let it turn into some vague "things got worse" meaning.
