Oklahoma and North Dakota. Various other states have restricted non-competes recently, particularly for low wage workers https://faircompetitionlaw.com/wp-content/uploads/2021/06/No... and more are working on it https://faircompetitionlaw.com/changing-landscape-of-trade-s...

I'd emphasize "one reason" and de-emphasize "always" :)

The site linked above likes to throw cold water on the idea that non-competes are bad for workers, startups, etc (e.g., ND and OK aren't famous for their tech industries), see blog posts at https://faircompetitionlaw.com/ ... my bias is the other way (particularly enjoying https://ssrn.com/abstract=2517604), but the evidence is complex. Fortunately the aforementioned changes should generate new evidence.
