That's either a lie, BS excuse or misinformation!
A "codec" is just software! No device supports "codecs", its a question of the software playing it or not. WMP doesn't play divx video, but plenty of software like TCPMP and CorePlayer DO... would anyone say WM does not support divx??
What about the ILBC codec that Skype uses to process audio?
Out of the box, WM doesn't support ILBC audio streams, which is the propietary format used by Skype (I think). Once you install an app like Skype, it magically does... so, would anyone say that WM doesn't support ILBC?

More misinformation: They claimed to me that WM does not support the AAC codec, specifically. Meanwhile, I've been streaming AAC shoutcast streams for years. Kinoma Play, CorePlayer, Pocket Player, whatever player is bundled on Samsung phones lately... they ALL do it! Then they say that Pandora is a "complex" application, more complicated than just streaming audio, and too difficult to port to all styles of WM devices. Meanwhile, "less complex" applications stream AAC just fine.
I think even the latest WMP plays AAC natively. That's not a limitation of the OS!

This is utter BS. At least say it like it is: You don't care about WM.
