Say what you will, but no one is forcing people to donate and no jailbreak has yet been released that wasn't free. If donations help by allowing these guys (many of whom are still students) to buy test devices, I'm all for itI'd much rather that, than wait for months while devs save up for a new device.
Bottom line: jailbreaks are a great gift, and I'll take them as I can.
I have no issues with donations. I'd think most would agree. I think the issues are when they keep posting cryptic updates. Now this jailbreak has probably has been most well updated that I can remember. But can't always make everybody happy.
