Enshittification arc means: An enshittification arc is the full narrative trajectory of a platform or product as it travels from beloved to barely functional. Borrowed from storytelling's 'character arc,' it frames corporate. There is no real cause for parental concern; it is descriptive vocabulary rather than risky behaviour. If your teen uses it, context will usually make the intent clear. A short, curious question about where they heard it is usually all that is needed to know whether to follow up.
