I think there's a misunderstanding here (and on Alpaca) about exactly what non-commercial means with respect to software licenses. Here's some related discussion: https://opensource.stackexchange.com/a/12074
The CC-NC licenses cover modification and redistribution ("use" in the license). They apparently have no bearing on whether you can personally run the software. And of course the outputs of the software are not copyrightable.
The base models are licensed under CC BY-SA-4.0 (not CC-NC).
"You are free to copy and redistribute the material in any medium or format, remix, transform, and build upon the material for any purpose, even commercially."
Oh, it shouldn't be the case. But anyone can easily finetune the Base model on the same datasets in a couple of hours on any consumer GPU with 8GB of VRAM and release it under the commercial license (using https://github.com/johnsmith0031/alpaca_lora_4bit).
