Don't believe I ever met JJ but I have known the man for a lot longer than I care to recall. In addition, I have had periodic interaction with the folk at GAM at EN over the years and know several quite well as friends and colleagues.
Not once can I recall ANY intentional inappropriate technical comment either from the man, himself, or his GAM folk.
Not a case of suggesting that they were perfect ... no-one is ... but I never saw ANY instance of anything which would have caused me to view them other than as a pretty professional mob ...
I, for one, would prefer to see an absence of unverified antipathetic comment in this thread ..
