You referenced the Ubuntu repositories but I'm assuming those files are
merged in from https://launchpad.net/~chromium-daily/+archive/stable which is
what I use to test websites.
Does this link help? http://code.google.com/chromium/terms.html#3rdparty
Out of those, what do you see as violators? Second, when I open up Chromium
and do about:credits, I see some ones listed in the program itself and not on
the above listed site. I did some searches and apparently there are plenty of
posts saying the licenses listed on the site aren't including the ones in the
programs itself. For example, "David M. Gay's floating point routines" which
has this license:
