Fortunately the ad gave me enough time to read the title.

Having to see an ad is a worse fate, to be honest.

I realized what it was because of the reply comment but I clicked it anyways because I am on Mozilla Firefox and by default YouTube videos don't autoplay.

iirc Google Chrome has some bizzare byzantine(?) rule engine that determines whether a website is allowed to autoplay and I suspect (with no evidence) that the rules are set up so YouTube can autoplay videos without prompting the user.

The HN username made me think twice.
