Most of JetBrains engineers was russians located in st. Petersburg. Since the war started, JetBrains claimed they've relocated all workforce from russia.
It shot down what is claimed to be "hypersonic" missle by russians. I don't know about "kinzhal" speeds, but the rockets are indeed was shot down a bunch of times. Speaking about "cyrcon" missiles, they do travel at the hypersonic speed but slowing down at the last miles of trajectory and can (and was) shot down too.
