I used to believe in the stereotypical copyleft anti IP ethos. In the modern day of corporate LLMs and disrespectful scraping, the lay of the ground is different and people understandably should be less inclined to open source their code.
I still do stuff in the hopes of it benefitting anyone - but not parasitic oligarchs who are responsible for the imminent destruction of the world and society.
I don't know if a reasonable number of spare-time creators, authors, artists etc. feel similar about these things, but if they do, I'd expect a lot more content under non-free licenses in the future, that might've been published openly otherwise.
