You're right in that (at least under IEEPA) the executive order doesn't seem to have the authority to ban free usage of these apps. In fact it also excludes regulation of "the importation from any country, or the exportation to any country, whether commercial or otherwise, regardless of format or medium of transmission, of any information or informational materials" (which include films so may include video clips as well). So maybe the implementation won't be a complete ban from the app store, and instead something much smaller scale that only prevents payments, or if app stores are asked to ban it, maybe the courts will strike it down.
