It has been ZERO DAYS since some GPL'd software made me "agree" to the GPL while installing it.

The GPL is not that kind of license: You don't need to agree to it. Agreeing to it changes nothing.

This just happens because installers have a premade "license" page and the GPL license seems like a natural fit.

But there's no point: You need to notify the user the software is GPL, but that's all.

@foone Now I want to make an installer that asks if you agree the licence is the GPL. And possibly random other licences. Maybe multiple choices and refuses to run if you identify it wrong like old school copy protection.
