Lots of people listen to the audio. It’s like a podcast, or having the radio on, which is fine in lots and lots of jobs.

Some people probably also literally watch it, but I know multiple people who basically use it as a radio at work.

Plus, never worked anywhere where half of everyone, including management, is more-or-less openly watching sports more than working during major tournaments?

And nobody's saying you're getting paid to watch YouTube all day. But video links get sent around, and people check out whatever 3 minute video. They watch during lunch. You know how it is.
