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.

The Bill of Rights is a set of constraints on the US government, so even to the extent it applies to the government when acting outside of its borders [0], it isn’t an imposition of US law on the territory of other countries, but a limit on such imposition.

[0] And it doesn't fully, see, e.g., Johnson v. Eisentrager, 339 U.S. 763 (1950), subsequently limited somewhat with the core holding retained in Boumediene v. Bush, 553 U.S. 723 (2008).
