Most people just call the language "JS" cause Oracle doesn't own that trademark. That's why you wouldn't be able to have a JavascriptConf but we do have JSConf. This is a long-winded way of saying that we already know what people would do with the freedom to speak the name of the language and it's nothing worth fearmongering over...

It's for the courts to determine who had what rights, but it's Oracle that is credibly accused of greatly exceeding the rights given them under the law
