"There are a number of words and phrases which we recommend avoiding, or avoiding in certain contexts and usages. The reason is either that they are ambiguous, or that they imply an opinion that we hope you may not entirely agree with. "

The jargon of copyright. There are some very interesting observations in here about the BSD license, intellectual property, etc... Some counter jargon is offered. I don't like a lot of it. People say "Open Source" because they don't want to imply "Free as in Beer." There needs to be a word that means "you can do whatever you want with the code" that doesn't also mean "we're giving the code away for free." There needs to be a word that encompases Copyrights and patents without implying property. There needs to be a word that replaces "theft" and "piracy" when discussing the unauthorized use of copyrights and patents. (I fear even saying "unauthorized use." We need more words...)
