Just look through the archives
and you'll see that every so often someone (usually but not
always from 'outside') will pop up in public
and claim that the IETF is run solely by and for the benefit
of large corporations. It isn't a particularly difficult
argument to counter, but the damage to the organization's
image is still there.
not much we can do about it, I'm afraid. part of the price of
being successful is having envious folks take pot shots at you.
the fact that their arguments are vacuous doesn't keep them from trying,
and occasionally, doing some damage.
