It's because they're misusing the term. Jevons' paradox doesn't apply to the simple idea that "cheaper code leads to more demand for code", that's just the concept of price curves.

Instead, Jevons' paradox refers to a counterintuitive rebound effect: AI tools make engineers more productive, which you'd expect to reduce the marginal demand for additional engineers (since the same output requires fewer people). In reality, this efficiency lowers the effective cost of software development, sparking even greater overall demand for new features and projects, which ultimately increases total spending on engineering talent.
