This is an interesting take. I think a critical missing piece from this article is how the use of coding agents will essentially enable the circumvention of copyleft licenses. Some project that was recently posted on HN is already selling this service [1][2]. It rewrites code/modules/projects to less restrictive licenses with no legal enforcement mechanisms. It's the opposite of freeing code.
