This is not correct. In typical use, copyleft means that you have to redistribute it as free software (GPL and variations). The opposite is “permissive”, you can use the software commercially, and charge others to use it as closed source. Copyleft is good for developers, permissive is good for companies.

So “free as in speech” is not even a good analogy. “Liberated” is more like it, perhaps I will start using libre more strictly…
