OT: How and why is this page overriding my control key, and how can I stop it from doing that?

I use ctrl+scroll wheel to zoom and it is very annoying when that behavior is overridden.

I think rather than overriding your control key, it's overriding scrolling. It loads up some smoothscroll javascript, and there's likely a bug someplace that's interfering with the ability to zoom. Holding control and pressing +/- to zoom in/out should still work.
