That's not a secret, also not the point.
The 2 main things about free software that offend capital are:
1. Capital can't appropriate it easily and enclose the commons because of capital's own copyright laws
2. Individual human skill can't be owned by a company: it's a rare form of workers owning the means of production
LLMs attack this by:
1. selectively ignoring copyright with the blessing of the powerful
2. eroding the value of human skill to rebalance power in capital's favour
