You find "Italiano" not "italiano" in the interwiki links. That is different. If you are in a primary school in Italy, your teacher will make you learn the difference :) .
If at http://en.wikipedia.org/wiki/French_language you click the "Français" interwiki link, you will arrive at a page where "Français" is spelled with a capital F because it is a title. The first words of that article is "Le français est une langue romane...". In the fact box to the right, the "Organigramme classification" begins with "Indo-européen" and ends with "Français", once again with a capital "F", because it is an element in a list. Clearly, the name of the language *can* be written with a capital F, when it is a title or an element in a list.
If at http://en.wikipedia.org/wiki/Italian_language you click the "Italiano" interwiki link, you will arrive at a page where the title is "Lingua italiano", but where the first words of the article is "L'Italiano è una lingua...". In the fact box to the right, there is a "Famiglie linguistiche" list that begins with "Lingue indoeuropee" and ends with "Italiano". Clearly, Italiano can be spelled with a capital I if it begins a sentence or if it is a member of a list.
If you try to deny this, I think your primary school teacher will correct you.
