Because they are closed protocals that can only be accessed by reverse hacking or permission from those companies (e.g. a form of their own client). But AIM and Yahoo will also work with an add-on from the extras-testing repository. (It's pretty much taken from Pidgin I think).

What are you on about? Afaik AIM and Yahoo are just as open as msn and ICQ. Either way the haze plugin supports all of them, and its integrated just as the other protocols. Haze is not stable yet though. In time.
AIM, Yahoo, and MSN (not sure about ICQ) are all closed protocals. E.g. the companies behind them (AIM, Yahoo, and Microsoft) don't support any client besides their own. Any client you use that uses their protocals (Pidgin for example) isn't officially supported or recognized by them. Thus when AIM, Yahoo, or MSN changes something you sometimes get breaks in Pidgin and have to wait till the developers of Pidgin find a workaround or whatever
Hence why Nokia is not bothering to offer this by default (answer to romanianusa) and hence why we have to go through something like Haze instead of having out of the box support.
