I don't understand how a company can have IP copyright rights on code that is inherently uncopyrightable (in the unlikely event scotus rules that way).
replyWorst case, meta will sue the programmer who produced infringing code.
replyI mean if the code is not copyrighteable that does not mean anything; it's just public domain code except that meta will just use good old security by obscurity to protect it. If somehow a meta programmer vibes code, say, VVVVVV, and Terry Cavanagh recognizes it on his facebook feed and sues meta, and wins, all that will happen is that meta will take down the copy of VVVVVV, will fire and sue the engineer that vibe coded it and call it a day.
