Those things require action in hours or days not months. An app ban doesn't need to happen on that kind of timescale. If it is that important legislation can be passed on the several months timescale that takes. Our Constitution doesn't really support anything like this under the legislative so the executive is where it all lives. In theory a different government layout could allow a different setup but that isn't what we have. You get "decided by the 535 membera of Congress in two votes and Presidential confirmation" or you get an executive branch being deferred power.
