I don't think Maemo was ever touted to be more free/open source than Android, at least not by Nokia. Sure, there are plenty of fan boys on this forum that have said that. For me comparing the openness of the two is apples and oranges.

Right now, Android is ahead in this area, thanks in no small part to the Replicant project. Replicant can however only run on a small number of devices. Android has always had AOSP but it's not possible to build the complete Android environment from that.

With Maemo, we're still waiting on the excellent work from the Fremantle Porting Task Force. Progress is slow but I think they will get there eventually, probably without all of the features and services that Maemo 5 originally shipped with.

Maemo for me, has never been completely about being open source, otherwise I'd probably be using a Replicant device. The draw towards Maemo is more about interoperability with existing Linux OSs: glibc, X11, the ease of porting existing software, etc. In this sense of the word, it's way more open than Android.
