Why does the U.S. export F-35's, but not F-22's?

They won't export any F-22's, but they will export F-35's.  Why is that?

the top rated post does a great job on the details, but this is ELI5, so here goes:

When countries (the US excluded) are buying planes for their military, they want to spend as little as possible while doing as much as possible. A multi-role fighter like the F-35 suits many missions and requires less support to deploy. The only countries with the support necessary to deploy a dedicated air-superiority fighter like the F-22 already have their own in development.
