As @FooBarWidget says, this is about donating to the Mozilla Foundation, not the Corporation (which builds Firefox products). I'm an employee at the Foundation, and these donations help us keep running and working towards our mission, backed by these principles: https://www.mozilla.org/en-US/about/manifesto/
All sounds warm and fuzzy to me. The Foundation should try to be more concrete in explaining what they do, and are currently accomplishing. Maybe this is already explained somewhere but I have no idea, and I'm a regular reader of HN, for example. Most people will spend even less time looking into it. The Mozilla Foundation/Corporation thing will only confuse people. Anyway, I'm donating kharma by explaining all of this. I'm done for now.
So what you're saying is that you have a negative/cynic view about Mozilla Corp/Foundation, but couldn't be bothered to read the rest of their website to find out whether your view is correct, and won't change your viewpoint until someone makes it easy for you?
I think they're saying it's not the best way to go about asking someone for a gift of money. It's not all that cynical to be skeptical of vaguely defined goals.
