Source code availability (and the ability to modify the code on a device) is the most important part, IMO , regardless of RMS's original intention. Do you feel that it's ethical that OpenAI is keeping their model closed?
No, because I think such restrictions are unethical in the first place. However, in regards to training, I think it might be a necessary evil to allow companies to ignore copyleft, so smaller entities can ignore copyright to train open models.
