Sure, there are a couple of buttons I can press to stop the video. Why do I have to? Find me one person who likes auto playing videos. The page was created with a deliberate annoying choice that I have to go out of my way to override.

Why do you think the author of this piece, to who you originally replied, has any control over this?

I'm not talking about pausing the video after it starts playing. I'm talking about a global setting to prevent videos from playing before you manually unpause them. Safari has such a setting, for instance.
