You are wrong. Disclaimers are a quick and simple way for users to let others know that there might be some specific view, or conflict of interest, or bias, so that the others can take that into account.
Disclaimer is exactly that; a disclaimer, it's a legal function. It's something you put in a contract or an agreement.
A disclaimer is generally any statement intended to specify or delimit the scope of rights and obligations that may be exercised and enforced by parties in a legally recognized relationship.
