They still were making the argument of relatedness based on teeth, and teeth that are not peculiar to aquatic animals by the way (some bats have similar teeth), and moreover, there is no claim Pakicetus was adapted only for eating fish that I know of.
Certainly, Thiwessen doesn't claim that.
Plus, you mentioned sharks having similar teeth, and Great Whites are known to feed on seals. So the whole teeth claims on your part are way overblown, and fact is these teeth are not similar to modern whales anyway.
