I think the license conditions are pretty clear. The main issue is that LLMs can not respect the license conditions.
The content I published under AGPL I want to be used freely under copyleft. Reproduction without AGPL does not meet those conditions. Stuff I published under CC-BY-SA, LLMs can’t guarantee either BY attribution nor consistently reproduce SA.
Whether training and consequential abstraction without reproduction is acceptable is a more difficult, subjective, and nuanced question.
