esr didn't coin the term, Christine Peterson did, and Tim O'Reilly funded the OSI compaign. Also, nobody used the term before OSI did, except with an unrelated meaning in the intelligence community.

>"Open Source" means different things to different people
And those people are wrong. The OSI definition is the definition. Those that want it to mean something else are trying to fool people, which we call "open washing."
Pedantically you're probably correct. However the OSI term is basically what people mean when they say "Open Source" now.
Much like many countries have a mile, if you started using Roman miles in England or the USA people would think you misleading
"Open Source" means different things to different people and not everyone accepts the OSI definition, there are even people who are angry at ESR for grabbing the phrase for himself and making his definition the most popular one.
