Not that it'll make as big a news item, but Rubin has responded in an Android blog titled:
I think I'm having a Gene Amdahl moment
(Gene Amdahl was the computer pioneer who popularized the word FUD, referring to the "Fear, Uncertainty, and Doubt" that competitors spread.)
Basically, Rubin said it was all misinformation, and that customization and open source was still the order of the day.
It's interesting that this whole thing barely raised a blip on Android forums, but was seen as a big deal on iPhone sites. There seems to be a huge lack of understanding of what "open" means, and there's blame to spread on all sides for that.
For example, I was just reading this morning on an Android site that the reason third party app launchers were available, was because it was "open". Not at all. They're available because the APIs are public, not because the OS source is.
