It would release a hornet's nest worth of issues. For example advertisers might change articles in which their ads appear in order to influence click-troughs. Then contributors will ask for a cut of the money. Then nobody will donate because they have to look at ads anyway. Then advertisers will start demanding from their sales people that certain content be changed or taken off "or I will remove my ads." So it should only be considered as a desperation move if their donations plummet.
