Pray tell, what "format licensing issues" have you ever run into with MP3?
Well, if you're going to sell a device or piece of software that plays back MP3 files, you've got "format licensing issues" to deal with, or get sued for patent infringement. MP3 is not open source.
That doesn't answer my question.
What "format licensing" issues have you ever run into with MP3?
MP3 is everywhere. AAC isn't.
Try legally decoding or encoding MP3 or even AAC in Linux or other open source software. Sure, an end user can add the codecs after install, but even that action is legally murky.
The average user, say my grandmother, who want a secure, stable, and relatively user friendly GUI based OS that will also run on her current hardware (can't cope with Windows XP as bad security and user ignorance is a lethal combination) is a poster child for something like Ubuntu. In fact her PC is still running a year after the Ubuntu install with barely any need for intervention, as opposed to her Windows XP install which would crap out routinely because of the complications of keeping a system patched while running as a LUA. The alternative was sticking to an Admin account and that certainly wasn't safe. Yuck.
Point is, when she wants to move into the realm of audio streaming from the net, she can't legally install the necessary components to accommodate most sources of the audio (Ogg vorbis and FLAC yes, almost everything else, no).
AAC is immune to the royalty payments on distributed content which so afflicts MP3, but just as MP3 has a licensing fee for implementing decoders and encoders, so does AAC. I really do wish that Ogg and FLAC can put a dent into the proprietary audio codec market-share. Each being free to implement and competitive to other codecs when it comes to sound quality.

In short, I have personally been affected by the patent encumbrance of both MP3 and AAC because of their inability to integrate into my Linux systems without running into issues of US patent law. These components don't ship with the software and as a US citizen I am not supposed to install the components after install. Even still, I choose the lesser of two evils which is MP3 as indeed its ubiquitous standing as the defacto digital music standard allows me a much wider level of support from software and hardware encoders/decoders. Also LAME sound pretty darn good to my ears.
