It’s because it’s not. Not really.

We live in the self-titled “remix culture” now. With media being so accessible, everything is up for grabs and subject to interpretation and re-interpretation. As well as re-distribution. When you put something online you essentially DO give it away. I think that’s just something everyone needs to come to terms with who is a content creator leveraging this platform. 

Like, theres a ton of my old crappy art on Derpibooru that I’ve either deleted or moved to scraps on my dA account. I didn’t put it up there, other people did. I can’t control that. My most popular analysis video is my oldest one that is absolute garbage in comparison to what i make now. I want to take it down but its out there. I’m sure someone has it backed up somewhere. Hell, I’ve seen some of my videos re-uploaded and subtitled in other languages.

My point is that, in an age of constant connectivity, on demand streaming, bit torrent downloads, software piracy, and mass media sharing, everything essentially belongs to everyone, because the tools exist for anyone to easily take any source of media they want and claim it for themselves, and do what they want with it. Every time you upload something you make, content creators need to understand that there is a very real possibility that that piece of content will be attached to them, and others, forever. 

If that scares you, reassess what kind of content you put online, or just stop using the internet for distribution altogether.

On the other hand though, you can look at the glass half full and take some solace in the fact that there are people out there going out of their way to keep your content alive and accessible  regardless of what the underlying motives may be. 

Your choice I suppose XP
