::::Since when has a definition in an article overridden secondary sources in a barely related article?  I'd be interested to see some evidence that supports this.  I can show you 10 articles that are described as free for the same reasons, at least until Palosirkka removed that claim.  Either case would be WP:OTHERSTUFF and making our own definition for the word "free" would be WP:OR.  I don't see a reason to disregard the definition used by numerous secondary independent sources.  
 ::::One could argue that the definition should be more ubiquitous but is Wikipedia really the place for us to be defining words?
