My guy, leaving out context can change whether information is dangerous or not.

Say I have a website that explains how to get clothes clean, and I recommend bleach. I also have a subsection "Danger: things you should never do with bleach!" listing dangerous things, e.g. "drinking bleach". Now Google pulls out only that list without the heading.

In your world, I'm responsible for Google showing information in the wrong context, which is nuts. I can't be expected to write everything so it's unambiguous, no matter how small a snippet you extract.
