Well, there's some truth to this statement regarding the functionality of the site, but at the same time I'd say that the design is harder than you might think; the work of creating designs, slogans, site names and copy text is underappreciated; it takes time and creativity to get those things right, and absolutely no work for someone to steal them. Not to mention any PR and press work done by twitvid to promote the site which could now be misdirected.
