To start with the basics:
- AAC is an open standard, everybody is allowed to use it.
Everyone can buy a license. It's not free, however. (Note that MP3 isn't free either - it is also covered by patent licenses. The only reason it's freely used is that nobody has bothered to sue shareware authors yet.)

- I guess everybody is allowed to modify the AAC file format in a way to add a DRM mechanism to it (Apple did it, and the Dolby Labs did not complain).
DRM doesn't change a file format.
You can add DRM to anything - even plain text - if you like. It's just a matter of encrypting some/all of the data and appending a certificate describing the license terms. Authorized players/viewers will respect the terms in the certificate. The encryption prevents the use of unauthorized players/viewers.
Apple could have put their DRM on top of MP3 if they wanted to. They chose AAC because it sounds better (and interoperability is no longer a concern once you've wrapped DRM around a standard format.)

- When you buy an iPod you are (or let's say you should be) allowed to play any songs on it, from whoever you obtained them (assuming you obtained them legally).
This is very misleading and incorrect.
Nobody is saying that Real can't distribute iPod-compatible songs. They can distribute non-DRM songs if they want and absolutely nobdy will complain. This entire argument is about their reverse-engineering Apple's DRM. But the iPod will not prevent you from playing non-DRM files (unlike players from some other vendors.)
Second, your claim that you should be able to play
any songs on it is far too broad. Using this argument, you may as well say that Apple is evil for not supporting Ogg/Vorbis, or FLAC, or WMA, or some other unsupported CODEC. Every product manufactured has a limit to its feature set. Saying that there should never be a limit is rather naive.
manu chao said:
- Apple is certainly not required to provide support for all file formats (e.g. WMF), but having a wide a choice certainly makes the iPod more appealling.
A wider selection is definitely better, but that's very different from saying it should be able to play everything you have.
From a product standpoint, there's more to it than just supporting what people ask for. Each new CODEC has development, testing and support costs. It may also cause hardware changes if the existing chipsets don't have enough power/memory to handle everything.

- You can right now play Fairplay-AACs on as many iPods as you like, in other words the owner of the iPod does not have to be owner of the songs. You can place any Fairplay-AAC on any iPod and it works.
... as dictated by the terms of the Fairplay DRM.
manu chao said:
So, why should Real not be allowed to place their own version of DRMed AACs on the iPod (violation of DRM patents notwithstanding)?
Ummmm.... because Fairplay is Apple's intellectual property and others have no right to use it without a license?
Because reverse-engineering any DRM scheme is prohibited by the DMCA laws?
manu chao said:
They just added a quirk to their DRMed AACs, so that they can be played on iPods as well, and not just with the RealPlayer, by allowing the song to be played even if no DRM control mechanism (as there is in the RealPlayer) is present, as it is the case on the iPod.
Maybe. That's what Real is claiming. It's not necessarily true. I haven't seen any technical analysis of Harmony-protected files yet.

Apple could easily break this via technological means, but this would be akin to blocking all MP3s which have been created on a Windows maschine. They could do this, no legal barriers to that but I guess everybody would consider such a thing unfair and unneccessary.
Or similar to changing undocumented APIs in OS updates in order to break programs that violate the rules. Which Apple has done many times in the past. And which most developers today approve of, because it kept Apple out of the trap of having to be backwards-compatible with broken code (one of the things that's hurt Windows over the years.)
