IMO He does have a point with regards to casual contributions and easy access to projects internals. I recently submitted patches to OpenWrt. I really have little spare time, and was only able to do that because it was so straight forward to get the whole thing running.
On a side note, I wish more FOSS projects would just move to GitHub.
On the sole grounds that loads of potential casual contributors (including me) already have a GitHub account and are used to work with it. It would remove yet another barrier to contributing.
Does he really answer the (frequent?) question "when will HP start shipping Linux on desktop systems?" with "a whole bunch of years ago"?
Isn't the question about: "when will I be able to go to hp.com and just buy a laptop of choice with Linux pre-installed?" (in which case, the likely answer IMO should be "not in the foreseeable future").
