Sure they do. If someone wanted to know where to get more information about the referenced item and buy it, that's added value.
It's only not added value if that's not something you want to do. Just as if, if you are not interested in the stock or its performance, it adds no value for you.
The argument here is not about whether it adds value - it does. The argument is over the type of value it adds, the cost of that value, and whether the added value is worth the cost - which is considerable.
