So my question is rather direct. Is it acceptable to IHUB for a moderator to receive outside compensation for a company they moderate?
Why not? The MODERATOR's role is to enforce iHub's TOU on that board. Period. Whether they are paid or not by the company should not be an issue vis a vis their role as MOD. The compensation issue is a legal issue, IMHO, outside iHub's mandate ie to provide a forum for discussion of the company in accordance with a set of rules, ie the TOU, that everyone agreed to abide by when they took their alias.
