I've seen someone around here manually adding a copyright statement to most of their posts and thought I'd see if others would be into it. It'd be unobtrusive and incorporated into the UI, rather than a piece of text in the post.
This is absolute nonsense. Sorry, but OpenAI with billions of dollars in MS money doesn't give two fucking shits about copyright at all, let alone some random ass nonsense in some schmucks Lemmy signature. Pretty sure most books have copyright and that hasn't stopped literally anyone ever, yet.
Looking at the link you posted, that was from 2022.
Notice anything?
No one fucking cares. Copyright is a tool for the rich to kludge the poor but not vice versa.
