"...I can't see why you'd bring that up."
Simply because they put it just under the names of reviewers and before any equipment that it was tested with. It appears that revealing "financial interests" was very important to them. I can't see why you'd skip that.
I also do not remember noticing "financial disclosure" of any kind in audio reviews which made this one even more odd. Maybe it was just a nice, but clumsy, try to appear fully legitimate.
