Its not about "billion-dollar companies' copyrights", but also about voluntary copyleft free software. If I license my code under GPL I don't want other persons/companies just whitewash that code through LLMs and use it in their proprietary code.

I agree with this, and I think that it is an open question whether or not training on copyrighted material is considered transformative or not. However, someone said that thumbnails of full photos are considered transformative enough to allow fair use, and LLM training is (in my opinion) clearly more transformative than converting a picture to a thumbnail. But we will see how it plays out.
