The problem with making things you make free, is that people as a whole are terribly selfish and lazy. They will take anything free and claim them as their own. Individually, tons of people will respect the wishes of original creators, but it only takes 1 single person who doesn’t care who will ruin it. The problem is the Internet has billions of 1’s. You can ask please don’t copy my freely available thing all you want, but it’ll never happen. There will always be those that will repost as thier own. From ideas to assets, nothing is sacred when it comes to the masses.
