Of course I would call a pirated movie free, because that's what it is.

Free isn't a synonym for good or legal.

[grodriguez100]

“Free” is related to the concept of property, which is a legal concept.

If something is “free” that means that you can get it legally without paying.

If something is only “free” by circumventing law, then that’s theft.

Anything at the store is free too, you just have to avoid paying.
