It was basically a business and price disagreement.
Negotiations fell through and then alternate options came up and threats might have came out.
Fine I'll get another team to finish up the JB or fine we will provide another alternate JB hack appstore so you're not the only monopoly available.
And so on. It's about profits and both sides have made plenty so far and will continue making more money with this new JB and so on. Its kinda pointless to try to take sides. I'm just glad we got a new JB for ios 7 and could care less if someone made more money than the other or whatever. Lets not fool ourselves, they're not doing this just for fun or just to be nice and provide a free service to everyone. There's money to be made and lots of it. And why shouldn't they make any? They deserve it.
It's always about the money. Which is fine, everybody expects to get paid in his or her job, so why should the evad3rs not be paid for there work?
If you look at @Musclenerds tweets is becomes a bit clear:

@i0n1c I absolutely agree that the open letter should have been timed with the release. But sauriks having fun made everything a rush

@i0n1c theres *still* stuff we wish we could reveal. Were encumbered by NDA with saurik (he sure covered his bases there

)

@0x8badfl00d but for instance in this case, our best estimate (at the time) was the racer was gonna kill 1 specific thing needed by 7.1 JB

It looks indeed like a business disagreement with the threat of a 7.1 exploit being burned in the process.
It would have helpt if the evad3rs had published the chinese connection at release.
Also it would have helpt if i0n1c had not cried WOLF again in his usual manner.
Sometimes it is better to address an issue without any wild accusations.
For now let the dust settled.
The evad3rs and saurik both have a vested interest in a continued collaboration so do other Dev's who might now be pissed off an threaten to walk a way.
For now i wish they just fix the ipad2 wifi boot loop issue!
