Can you elaborate on what do you mean by "even"? There is no other big name mobile distro that actually has a separation free and non-free, or allows to use only free packages so that there is some functionality.
This is IMHO a case that MeeGo, in this example, is by far the best and possibly currently only relevant freeish (future) mobile distribution there is at the moment, but since it is so close to our actual traditional distributions, some start to bash it that it's not as pure as Fedora or Debian (main). If the alternative is the closed development and "throw all FOSS history away" model of Android, or anything else nowhere near MeeGo in its openness, what's the point except polluting discussion forums with non-relevancy? The majority of FLOSS users even understand that there is Debian non-free or even the Ubuntu model of shipping a small handful of restricted software by default (unless told otherwise).
Regarding the UX stuff: I've no interest either if manufacturers are doing closed UX:s or not - of course they are doing, and they should be doing that. The fact that there is still going to be also free UX:s is a huge contribution to FLOSS world where we do not have enough touch friendly software yet. I'm going to be an extremely happy Debian packager of MeeGo software if I just have the free time of it. I see MeeGo's contribution currently as the best possible contribution to free software phone users - and how many of (you) potential complainers are actually using purely free software on their phone _now_? I've been using FreeRunner as my only phone since 2008 Autumn.
So please, there is so much more important stuff to discuss than these details. The freedom question is more relevant in the niche area (mass-market wise) of running only free software on some specific _device_ (not what there is available in the distribution repositories), and there I'm quite positive MeeGo's N900 adaptation team is making quite great progress as well so that also I'm going to have a potential successor to Neo FreeRunner one day. There is again no other current phone device than Nokia N900 that you can do calls with free software - supported and developed by the manufacturer.
So I'm giving them B+, mostly to say that they are doing better than anyone else by far (hence so high grade), even though there is much to improve (and ship).
