Jaco: "Normally open source means the source is open to look at."
Nope. Open source means exactly what the Open Source people said it meant - it wasn't a widely used term before they coined it. Whether or not you aim to adhere to the trademark requirements, calling "look but don't touch" stuff and "shared source" stuff "open source" is just deception.
"So open source don't need to be licence free."
Yet more deception here, too. Open source software generally has a licence attached, unless you're thinking of public domain works.
