It’s time to post this again: Copying Is Not Theft!
The arguments we’ve seen for many years, erroneously call copying « theft » in this digital age.
All Creative Work Is Derivative
In some countries (looking at you, USA – but EU has many problems too), Copyright is automatic and there’s no way to opt out. But you can add a license granting some of the permissions copyright automatically takes away.
Creative Commons, the most widespread brand of license, allows its users to lift various restrictions of copyright one at a time. But, that’s your choice to use it or not.
