Derek Morrison on the oddness now prevailing in the online content and ebook market: "today any mass automobile manufacturer producing a vehicle, no matter how desirable, that could only be fuelled at a specific chain of garages would soon be out of business. But yet here we have just such a scenario with developers and distributors of ebooks and other vehicles attempting to impose such constraints or 'tethering'; in some cases, e.g. Apple iPhone and Apple iPod, with considerable success." But hey, such content is 'free' and 'open', isn't it? Isn't it?
