I've always felt like there's something fundamentally flawed with open source licenses. It seems that they are all promoting the openness of a fragment of code but at the same time twisting your hands ever so slightly when you start using them. All while different licenses are engaged in a fight as to which is more open. For many years I thought that MIT is the most open one. That is until recently when I saw wtfpl [1] and truthfully I fell in love with it. At some point I'll update everything I've ever open sourced to that and I intend to use it for all the other projects I plan on open sourcing, though I am a bit short on motivation to get to that lately(for personal reasons, not because of lack of interest or burnout or anything).
