Ryan has always stated there will not be censorship of original content. Copyleft, can be used on A regular basis, all it permits is creating derivative works from other persons creations. This is also mostly covered in fair use laws. Allowing, parody, response and sharing other peoples content if it expounds on your original points. Embedded 3rd party content is already sourced, but if you use it as a main point or actually copy from it you should also make it clear in your writing.
An example of this can be seen in this post: https://www.yours.org/content/cancerous--distraction--or-smart-people-wanting-to-be-right--84f743bb9326 half way down the bullet points included in my article are all copied directly from another article. In order to be used I needed to link and, in fact, I encouraged people to read the entire article. This is covered under current fair use laws, with or without a disclaimer.
Parody also falls into this. I think parody is self explanatory.
Commentary or response works are covered under fair use. If I link a video article etc and my full amount of original comment is critiquing it point by point this is also permitted under fair use. The "skeptic community" fought this battle with YouTube when calling out the stupidity in the Social Justice Warrior videos.

Then you have completely derivative works that uses other contents copyrighted material to create something new. Images that are marked for commercial use or reuse with modifications can be used without citation. I use images that are marked this way in my blogs because I'm not an artist. but I want the blog to be visually appealing. These images. always match the content and are never linked to the host to keep from using bandwidth. I do record the artist info, when possible, and record Google search modifications to prove it was labeled that way if the artists changes mind. An example I just used a photo of rock em sock em robots. I pasted a bitcoin core logo on one head and a bch logo on the other. the original photo was not mine, but marked for reuse with modification, so in good faith, I can use and modify without citation.
derivative works also extend to guys like Pogo, who takes snippets or samples of a musical or video and creates new art out of it. This example pull. words spoken in Star Trek TNG, add a musical background, a little autotune and you have something amazing: https://youtu.be/bl5TUw7sUBs

Somewhat off topic but I was still wondering about policing comments (I forget what the solution to this was), as someone could just buy what's behind the paywall and then comment on a post the material that's behind the paywall (I don't remember if you can remove comments on your posts or not).
