The increase of freedom of the users is an indirect side effect, intentional or not, which, as you put it, can happen, or not. But a direct effect, which is guaranteed to happen, is the loss of freedom of the manufacturer. Whether that's a good thing, that's another topic.
The increase of freedom of the slaves is an indirect side effect. But a direct effect, which is guaranteed to happen is the loss of freedom of the slaveholder.
That's certainly a perspective, specially given how slavery is often regulated into law.
But I digress, there's a plentiful discussion to be had about the ethics and morality of freedom/regulations, but my point is how there is, in fact, a dichotomy between both and it isn't just framing. Which, in a sense, you just corroborated.
