You don't understand the implications of your own words:
"having a financial interest in the outcome of a debate makes
anything that person says an advertisement for his financial
interests, not a fair assessment."
is substantially different from
"render his arguments in the debate inherently suspect."
Do you understand how? Hint, see my comment regarding "hyperbole"
and also consider the relationship between the qualifier "anything"
and universal quantification.
I think if you think a bit more carefully you will come to see how
your original statement was indeed fallacious ad hominem. (And that
specific example remains so regardless of which common approach to
informal logic you take ie whether you choose one that is more or
less sympathetic to ad hominem in general.)
