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.
@abstractcode @foone That's starting to sound like that game Agreeee that's been doing the rounds lately https://store.steampowered.com/app/3757210/Agreeee/
Agreeee on Steam

Can you 'play' this game!? To play the thrilling action game, you must agree to all 12 terms and conditions.
