I wonder why they didn’t train off Kimi 2.6, I hope is it because they already had a good base and not that they messed up that relationship.
There's nothing to mess up. The license is MIT w/ attribution, and the attribution clause can be easily sidestepped w/o any legal repercussions. The "drama" was simply content creators going nuts over some misunderstandings and poor comms from some kimi related devs.
