"Star Wars" fans will remember that Master Sifo Dyas contracts the Kaminoans to build the Republican army years before the events of "The Clone Wars." Unfortunately, Darth Sidious, aka Emperor Palpatine, becomes aware of the army and decides to use it for his own purposes. By the time the Empire is created, Palpatine sees no need to keep funding the expensive creation of clones, sending Grand Moff Tarkin to assess the Kamino production line and the Bad Batch themselves.
Tarkin quickly comes to the conclusion that the Kaminoan forces are no longer needed since it would be cheaper to conscript normal citizens into the Imperial army. And just like that, the contract is canceled.
The Kaminoans are understandably bitter about the situation, and one of the senior officials sneakily helps the Clone Force 99 escape the hangar at the end of "The Bad Batch" Episode 1. It's not yet clear whether the Kaminoans will work directly against the Empire from here on out, but it wouldn't be surprising if they do.
A moment in the campaign of 2005's "Star Wars: Battlefront II" game sees the Kaminoans grow their own clone battalion to free the planet from Imperial rule. But because it's never been mentioned since, it's unknown whether that event also took place in the new canon that Disney set up after it acquired Lucasfilm in 2012. It already seems like the Kaminoans aren't happy with the Empire's decision to stop growing Clones, so who knows? A Kaminoan uprising may be on the way.
