HN: "Facebook, Google, and other Big Corp being gatekeepers is censorship and horrible!"
Also HN: "The OSI is the One True arbiter of the term 'Open Source' and anyone who uses it in a way that disagrees with the OSI is dishonest and trying to cheat you!"
If what you want is a situation where anyone can just call anything open source and individual users have to manually re-check all the licensing for any given project that gets posted to HN to make sure it doesn't add additional restrictions or conflict with the common MIT/BSD/GPL, I'm pretty sure that's already happening. There isn't any big corp gatekeeping -- they don't care if the community gets stuck dealing with fallout from these new licenses because that means they didn't have to pay the legal costs to get it tested in court. And in the meantime if the big corp really wants to be a customer they'll just ask to buy a standard proprietary license because it's cheaper and doesn't involve legal.
