Why would it be OK to say "provide confidential advice" but not "provide confidential help"? To me, the latter form seems wrong, but I can't explain why.

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information. If this question can be reworded to fit the rules in the help center, please edit the question.
Advice: "an opinion or recommendation offered as a guide to action, conduct"
Help: "to give or provide what is necessary to accomplish a task or satisfy a need; contribute strength or means to"
So I would provide confidential advice in a business to business situation, but I would provide confidential help with my friend's homework.
Both are correct grammatically, but the latter is probably used less often (there aren't as many situations where help need be confidential).
