Any #MIT license nerds out there?
Quick question: I've discovered a client has thrown together a bunch of different AI generated "apps" (hosted around the planet on Vercel, Netlify, etc. On public links...but that's another story). These apps seem to use chunks of React JS - not React JS as a whole, just parts of it.
Now, the whole thing does not include the MIT license so I suspect it's in breach anyway, but I was wondering what the situation is around tearing some parts of the project up and using just those parts without accreditation to ReactJS? Seems a bit iffy, right?
