are you able to say more about this (specifically that the researchers who left were concerned that qwen models were being closed sourced)? I was under the impression that the chinese labs and their employees aren't particularly concerned about ideology/safety/whatever and were just releasing open source models because it helps with publicity and does the most damage to the US AI labs. (and to be clear, I strongly support open source models, I just doubt that the Chinese labs and their employees are actually motivated by morals).
