I mean, I can't give you a source more infallible than...Google...but as a native English speaker, I can say the word "less" means less than something that is "free."
And listen, I'm not saying I agree with this opinion. In fact, the example I provide is proof that an argument over words like "less" and "free" are inconsistent at best. If anything, I believe the English language is pretty fucking stupid, but here we are.
At the end of the day, please be careful with your animal meat, friends!
