TL;DR
It will disappear soon after the funding campaign is over. That’s what I read anyway.
I was going to post this reply in the thread below but here goes.
Who do you help when you support the Tor Project?
Let’s get serious. You enjoy this for “FREE”. Nothing is free.
I’m not a heavy Tor user; very light in fact. I donated last year and will do so again (when I decide to) because it’s an important project. I still get the popup to donate anyway. I would be worried if they did not show it because they knew I donated.
Read that thread. They don’t ask for your fortune; just anything. One (maybe two) less mocha latté capucinno frappé at $6.50 for this month. Most of us can afford it. Yes there are people who cannot. It’s not a good cause. A good cause is donating for something you do not use. A way to relieve your conscious. This is something you use every day. Kinda like a way to make sure it stays around.
One click is a small price to pay if you decide that you cannot donate.
