In the case of slavery - we changed the law.
In the case of copyright - it's older than the Atlantic Slave Trade and still alive and kicking.
It's almost as if one of them is not like the other.
Use this newfound insight to take my comment in good faith, as per HN guidelines, and recognize that I am making a generalized analogy about the gap between law and ethics, and not making a direct comparison between copyright and slavery.
Can we get back on topic?
