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.
