Imagine that landline phone calls were initially free and had to be "monitized" via adverts. Or, if it ended up being the case that they couldn't be sufficiently monitized and thus were considered a "failed business model". This age of freemium is producing all sorts of wack products. Why can't I just have a phone company that adds Twitter-like functionality in my paid plan. Oh right, because even though it's all "free" it's all proprietary and incompatible.
