I mean, this isn't consistent with the usual definition of public, especially on sites that let you share content: * YouTube uses "public" for viewable by everyone and discoverable; for something that should only be accessible if the URL is shared, then YouTube uses the term "unlisted" * Facebook uses "public" similarly More generally, "to publish" (related to the adjective "public") means to make something generally known, as opposed to simply sharing with a closed group (even if they can share it too).
