There's nothing special about "video service" nor is that even a relevant concept to discuss and in no way contradicts anything I said. If you're going to claim otherwise, please be specific about this alleged contradiction so we can have a meaningful conversation. Serving data is serving data. Hosters have to put effort into disguising/obfuscating a URL to make it not be a static link (and thus completely useful for HTML5 video/audio use, or pointing others to download and keep, or something else).

If a hoster doesn't want one to distribute the files, that is the issue. Not whether one distributes them for use in an HTML5 video/audio element, or downloading for local storage, or use in some other way.
