American laws also have universal jurisdiction (for example, the Bill of Rights doesn't say, "unless you are located outside the US"). Most countries do not explicitly recognize that their laws do not have universal jurisdiction.
In practice, it is easy to pick out the situations in which there is "practical" universal jurisdiction, vs "theoretical" universal jurisdiction.
A Colorado company selling locally in Colorado falls in the "theoretical" bucket.
