@Winocm is not requesting donations.
1) He does not support the notion of donations in his case as it's a hobby as he mentions time and time again.
2) He released the backbone to jailbreaking, he did not release the tool. Meaning only experienced hackers will be able to take advantage of what he's compiled
3) The person that's begging for donation is the real scam. There're a few freshly made Youtube accounts that claims that they're in the process of putting this backbone together to create a tool to jailbreak. He asks for donations to have "early beta access". One, he has no proof of an iOS 6.1.3/6.1.4 exploit, two, once there're actual tools or progress being made, or once he's accrued enough money over a period of time where it's "logical" to spend on making the jailbreak, he'll pull the project down along with any Twitter accounts, Youtube accounts, domains, etc, and high-tail it with the money
4) @Winocm said he was working on a JAILBREAK, not a method to port Cydia onto your device. Jailbreaking does not mean a tool that ports Cydia into your device at your fingertips. Jailbreaking means allowing your device to run unauthorized or non-Apple support commands/codes/projects/etc. He promised a JAILBREAK, not a TOOL. So that means one, he's not duping anyone, two, he is not begging for money, and three, he delivered.
5) @Winocm is not Geohot. His work clearly outpaces that of Geohot and does the job much more efficiently than Geohot has ever done.
Just because someone slams allegations against him on Twitter doesn't mean that's the first thing that you believe. Just because he didn't release an actual tool to jailbreak 6.1.3/6.1.4 for the illiterate, everyone thinks he's a bad person and should burn on a stake.
