No, the first time I heard someone complain about it was at Red Hat.
Citation? I assume you mean Fontana complained about it, since he's the GPL expert at Red hat?
The second through nth times it was people on my GPL committee, which was most distinctly not the big firm committee.
I was on that committee. Note that it included Larry Rosen, who, while not at a big firm, is one of the people who has generally looked for ways to get around copyleft.
Allison Randal on that committee had complaints regarding seeking simplicity, which are similar to Fontana's arguments. Also, as you'll recall, I argued with her (IMO successfully) to point out that GPLv3 needed to be more verbose so that people could understand better copyleft policies.
