What's especially interesting about the HTC case is that they'll habitually trot out the 120 days claim (up from 90 days a year ago) right up until the point where you actually start threatening legal action, at which point the source will usually suddenly appear on their website. The impression I get is that their delaying is nothing to do with any technical requirements on their end - it's purely to keep the source private for longer out of some kind of desire for competitive advantage.
