Generally autoplaying anything for me is a no-no. If there's a setting to stop it, I have it set in advance.

I love it when the house gets woken up in the middle of the night because I scroll down on a page.

Yes, is there a logical extension to "UX" design which includes "non-user in proximity experience"? NUIPX perhaps?

For bonus fun, if you try to stop the video, it starts again as soon as you scroll any amount. Great job, guys!

Sarcasm?

Nope - I actually quite like it in this instance. I don't tend to like it in the general case though, as it's usually done poorly.
