> the word does deny something: usually of the possibility of bias.
That's precisely why I objected to its use in the context it was used here (and other places where it is colloquially used incorrectly): by announcing you worked on something, you reinforce the possibility of bias in the post while taking partial responsibility for the work--it does not disclaim or subtract bias or responsibility.
Not sure why you're getting down voted. Perhaps because people find the tone too snarky. You're right though. It's a mistake I see all the time here (and it secretly bugs me haha). Disclaimer in this case would mean: "I say this, but beware I'm not involved in this so I'm probably wrong". Which is exactly the opposite of what's intended here.
Disclosure would work just as well, and is in fact more accurate!
