Taig, a Chinese app store written in Chinese, is rumored to sponsor $1 million to "evad3rs" - jailbreak development team - to jailbreak for Apple’s iOS 7.
The jailbreak team has noted in an open letter on its website that they have received compensation from Taig,
“Yes, we have benefitted financially from our work, just as many others in the jailbreak community have, including tweak developers, repo owners, etc. Any jailbreak from us will always be free to the users but we believe we have a right to be compensated in an ethical way, just as any other developer.” And the compensation is rumored to be about $1 million.
