TII's Falcon 40B AI model royalty free for commercial and research purposes

"Waived royalties" - has it been released under a different license or are there some shenanigans going on? The initial license seemed so sleazy I don't want to touch it. Unless it's being re-released under a known open source license, I'd still stay away.

(And per that twitter thread, the license hasn't yet been updated anywhere.)

Edit: looks like they changed it to Apache 2.0, so it actually is an open source model: https://huggingface.co/tiiuae/falcon-40b

I still don't trust them.
