Digital artifacts are the modern form of the means of production. Making digital artifacts available under a libre/free is giving these modern means of production to the public by putting it into the commons.

By requiring an interaction and explicit permission, you're putting yourself as a gate keeper to the means of production. In the best case, the uses will depend on your temperament at the time of request. In the worst case, such as a state backed morality commission, this could lead to corruption and abuse.

Part of capitalism is the ownership of private property, including intellectual property. If your focus is on making sure you have control over your work for things you think are moral, then the modern copyright system is in place for you to keep that control.

My focus is on empowering people with tools and making sure those tools aren't restricted in their use by a small oligarchy.
