TL;DR: The big tech AI company LLMs have gobbled up all of our data, but the damage they have done to open source and free culture communities are particularly insidious. By taking advantage of those who share freely, they destroy the bargain that made free software spread like wildfire.
No, its copyfarleft. Both it and copyleft USE copyright. I recommend you the Telecommunist Manifest on this topic, and you can find the stupid take of the FSF on this in here. I don’t want copyleft anymore, I don’t think it is enough. The FSF’s justification is hipocritical and coward as they state that “…embedding that desire (ethical behavior) in software license requirements will backfire, by legitimizing fundamentally unjust power over others” while using the power of copyright themselves, and in a world where we already see bad actors profiting from collective work.
Edit: Adding to this, the first word of the GNU GENERAL PUBLIC LICENSE is Copyright lmao
