Why I used to prefer permissive licenses and now favor copyleft

https://vitalik.eth.limo/general/2025/07/07/copyleft.html

I strongly prefer CC-Zero and in general don't like the idea of copyrights and imposing on people what they should do with things I create to be public (threatening legal action, no less, if theoretically if they use it in some way I don't approve of). If I wanted control and restrictions I'd just kept it private.

(But that's just my own opinion, I try not to impose, some people like copyrights and other legal privileges and I don't intend to convince them otherwise.)
