The entire reason for these talks was the history of development of the computers.
Chuck Peddle back in 2007 was brought in to talk about the PET. no one expected him to talk about the current state of the PET. Bob Russel and Bill Herd were also there to talk a bit about post Peddle and PET 8Bit
Bill Herd in 2012 was brought in to talk about the development of the 8bit line he was involved in through the 128.
Dave Haynie was brought in to talk about Amiga development he was involved in under Commodore.
Are there other people who could have talked about these things? Yes. Haynie gets a lot of buzz since he goes out and talks about it. Herd is the same, he goes out and talks about it.
I don't see a reason to be negative about the guy for, when asked, saying yes he will go give a talk about the time at Commodore
Evidenced by the people who attend these, there are folks interested in Computer history like this. Not just people who were into the scene back then but also people who are new to it or were owners of competing computers back then.
Don't bust on the guy because he doesn't talk about OS4 or MorphOS (and I do use and love MorphOS on my PowerBook) since those aren't what he was involved in engineering for.
He talks about what I expect him to. Amiga 2000-4000 era and AAA which was in development when Commodore went under.
And finally, Dave gave his explanation about the MorphOS statements back on April 2011. Seem pretty cut and dry to me.
Far as I've seen, not that my research is exhaustive on it, the MorphOS folks haven't exactly come out and stated they have not used any Amiga code, or Phase5 code which is the code in which Commodore owned code was seen
