I'd take Google's definition over a definition on a website anyone can edit
this is the most handicapped thing i've read on here in a while
wikipedia hasn't been "a website anyone can edit" for many years.
go and try to vandalize any article or post false information without a source, it will be deleted by automated bots or moderators within minutes, if not immediately.
not to mention that like half the articles on wikipedia are literally all semi-protected so only moderators or certified veteran editors can edit them.
