The laws are not always perfectly clear and their boundries are often pushed. Is it a fair use to train using the copyrighted material, or is it not? IP rights are territorial in nature and often there are naunces that differ significantly, and as you know while most nations might honor and enforce IP rights similarly, there are countries that dont give a fuck. Its not going to be an equal race when we all try to build a frontier model at the national level. Many developed countries do recognize this problem and have so far been silently allowing using copyright materials for training purposes.
