I guess Apple is big enough that they no longer worry about infringing on other people's trademarks. FaceTime has been an instant messaging platform for years, it's not like they're new. Lots of large financial firms use them.
Come on Apple, how do you expect others to respect your trademarks if you don't respect other?
They've always been compliant in publishing the GPL'd source that they use or modify, but they're releasing this for the wrong reasons. One person on the archosfans forum (archilles) published code to jailbreak this model and get access to all the plugins, without publishing the details. Others have been very forthcoming with the internals they've reverse engineered.
Archos' response has been to put out an Angstrom Linux distribution, while wiping the DRM keys from the device. Even though they are distributing this, installing it will immediately void the warranty. This is certainly not a sign of good will. The only reason this being published is to try to stop people from hacking their boxes.
The disks are getting full; purge a file today.
