I think it is disingenuous to talk about "freeloading" when the license that the content was released under, was freely chosen? No one is forcing anyone to license content under Creative Commons...
If it is possible to contribute to WMF monetarily, by volunteering in myriad ways, etc., and it is not supported in any other way, such as ads, subscriptions, corporate sponsors, then technically anyone who reads Wiki*edia or downloads content from Commons, Wikisource, etc., is freeloading without contributing anything.
The WMF doesn't mind, certainly, that there is a large plurality of freeloaders: that's their very model. But they also need money and volunteers to run everything, and that's why they're mugging you with dialog boxes.
If you don't have the time, effort, or expertise to volunteer for WMF, consider donating voluntarily, because you certainly do benefit from their mission, and see above about fungibility.
Frankly, though, it is far, far better to attempt to volunteer in some capacity, because as has been demonstrated, they're financially pretty flush, whereas the volunteer situation is always fairly desperate on several fronts.
