The purpose of a Hello World, however, is not to showcase language features, it’s to provide a minimal program that produces output, to test that your dev environment is working properly, and for you to learn how to operate it. Adding any unnecessary complications to it only adds further sources of error.
Do you think real people will get confused and think the only way to write hello world in bog is using a variable ?
Or do you think most people will automatically adjust and think "hello world in itself doesn't show much, so the author decided to include something more informative and keep call that hello world" ?
Are you talking about CERN's decision to put their web client and server source code into the public domain in 1993? It seems like a stretch - to me - to attribute the success of the web to that decision.
It was probably a big factor. Gopher was a real competitor initially but the University of Minnesota which owned the IP started trying to charge license fees in Feb ‘93- I suspect CERN’s decision was a response to this as well as MOSAIC’s similar efforts around the same time.
You couldn't predict that CERN's protocol would win, but you COULD predict that a public domain protocol would win.
Proof:
For every pair {protocolX,protocolY} where functionality(protocolX) = functionality(protocolY) && isPublicDomain(protocolX) == true && isPublicDomain(protocolY) == false, then speedAndUtility(protocolX) >> speedAndUtility(protocolY).
