I understand the need to do things that aren't the specific thing you want them to do (i.e. run Wikipedia). But I don't see the need for this. What is actually bad about people not recognizing your brand correctly? They sure as shit recognize the product. If someone can provide an actual reason why this should help the foundation carry out its work, I can be convinced to be in favor of it.

If they are a net negative in the world, I would withhold donations.

It's not about good or bad, it's about opportunity cost. Most people have a limited budget for donations.
