ORA has asked me to sign a CLA for my participation in a panel at OSCON 2014, where I took a position against CLAs. They claim to "not know" about the multi-year agreement I signed with ORA back in 2000 for presentations at their conferences (which granted them rights under the FDL).
I've offered them back CC-By-SA-4.0 in a heavily edited version of their agreement. I suspect they'll reject this, but the story is ongoing. I'll make a full blog post when the story ends.
BTW, the official document editor for OSCON 2014? Not LibreOffice: it's Microsoft Word. (obviously I imported it into LibreOffice and sent them a track-changes version)
