Are you saying Ofono isn't as open as it has been purported to be? Or are you comparing Ofono and the telephony stack that's actually in Maemo 5?

If the former, would you please point out the pieces that are closed? I've missed that announcement or discussion.

If the later, please further remember that Nokia made it clear quickly after the announcement of Ofono, and long before even the first pre-alpha SDK for Maemo 5, that Ofono would be part of Harmattan, not Fremantle.
