They did that kicking and screaming after many, many promises of finally opening up and never doing it, huge undocumented code drops, massive style inconsistencies and so on. It took years for Webkit to get around to the level of openness that it's at today, and being cynical, that wasn't because Apple wanted to give back to the OSS community; it was because they wanted Nokia on board. I contributed some very minor portions back in the KHTML days, and am friends with all of the original KHTML developers, so I watched this unfold. To be fair, this wasn't the fault of the Webkit developers, but as mentioned in the article, Apple's ultra-secretiveness and development timelines.
