Nobody is confused about how it's currently working. The whole complaint is that there isn't a way to donate towards Firefox and have any confidence that's where the money will go. There are a million social justice charities out there and zero dedicated to non-chromium browsers. A lot of people are disappointed by that. Anyone who wants to fund Afrofeminist conferences can do so directly.
Sure Mozilla can spend donations how it wants, but donors are free to not donate as well. For years many people have been saying that they want to support Firefox without all of unrelated social projects, but Mozilla has refused to offer that. I expect that a lot of potential donations have therefore not happened.
Quite a few people would donate for Firefox development, but they can't donate to Mozilla because Mozilla spends the money on other stuff. Until now, as Google's lapdog, Mozilla didn't need donations, so that wasn't a problem (for Mozilla, it did however result in firefox getting 2.62% market share).
To reinforce this, I'm a stingy bastard but I'd give them 5$ a month if I could donate them to the browser development itself since it's the program I use the most.
