It's because a reusable letterpress metal plate of text is called a "boilerplate" because it looks like the manufacturer's nameplate on a steam-train's boiler. That led to any reusable block of text being called "boilerplate".

I've used wheel mice on the Mac from the time the Microsoft USB wheel mouse came out, back when there was a Mac driver that controlled classic Mac apps by looking for scroll bars and sending events, licensed from an Italian developer.
I myself added native wheel support to some major Carbon apps, and convinced other engineers to do it, as I was at Microsoft MacBU at the time.
But anyway, when Apple decided that scroll wheels should work the other way around, I gave it a try. I soon acclimatized to it and never had to change the default again. I would recommend all Mac users try out the "natural" setting and see if you get used to it.
Now explain why I HAVE to invert the y-axis in Halo on XBOX (any version of either). I tried but I can not adjust to the default.
