Just a reminder to people, All The Tropes is a fork of TV Tropes, but everything is under a free license and has no advertising. TV Tropes uses a nonfree license.[1] The same page is available here: https://allthetropes.org/wiki/Unintentional_Period_Piece
Why bring in ideology when you can simply state that TV Tropes is Creative Commons Attribution-NonCommercial-ShareAlike licensed, while allthetropes is Attribution-ShareAlike licensed?
Eh, it was just an interesting article that was featured on HN a few days ago.
Mainly it's just one more reason that I'm still upset at TV Tropes for relicensing things I wrote without my consent. They took a lot of things that used to be community property, and decided that they should be the only ones to make money off of it. And they've gotten away with it because none of their users really know copyright law. I guess really, it's because sometimes ideology matters.
