Renee fights against Oh No They Didn't, a group of internet assholes*. The problem is that on the internet, people tend to repost things and think that it's OK as long as they are sourced. It's a big clash of ideas- the internet's ethic of spreading information and the older idea of protection of those ideas. There's a lot of layers here- the issue of women of color getting credit for their ideas, the restriction on the spread of discourse, the fact that ONTD might be full of people who are assholes on the internet.
And when you have internet assholes, many of them will be racist and sexist, which of course has its own problems completely apart from this clash of values over copyright and intellectual property.
*I am also an internet asshole. I'm really trying to recover. I'm fighting the urge to be an internet asshole about this. I'm going to be kind, gentle, and never make fun of anyone ever again. *Oh so hard*
