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 Fun fact: when I was much much younger and was only beginning to interact with open source software, having previously mostly been exposed to restrictive and threatening EULAs, I was trying to read and comprehend attached GPL licenses, expecting to find some sort of a catch, or a small print, I would trip on sometime in the future.
