Indeed, as I keep on saying, we are not entitled for their work. However, attempting to draw good will by appropriating the meaning of the term is, to borrow an expression from Bryan Cantrill's amazing Lisa '11 talk about Illumos [1], "Shitting in the pool of open source and disgusting corporate behaviour". Shame on Facebook, 01-AI, and everyone else that keeps on doing this.
