"I pointed out that Sun managed to open a gigantic and completely closed code base (with a long history), in far less time than it took Fedora/Redhat to open up the supposedly 100% open-source build infrastructure of a 100% open-source project for public use."
It wasn't open build infrastructure at all before and what was used internally was completely unusable outside of Red Hat. It had to be written from scratch before it was used for Fedora as I have already indicated earlier. It wasn't 100% open source either. That's just two of the several things you have got wrong in this discussion. This discussion seems completely unrelated to the article at this point even if it was tangentially related earlier and If you got more questions, feel free to email me and I will happy to tell you all about it.
