Heck, they don't even pay a good fraction of their bandwidth because they put caching box in your ISP location to reduce loads. This is a huge privilege as ISPs won't let any random companies run equipments for free in their network, which is one of a huge barrier for any YouTube competitors.

Youtube expenses is revenue share with creators and hosting untold hours of video, over 500 hours uploaded per minute, that others just don't have to deal with.

It "makes sense" in that, unlike those two, YT has to deal with thousands of hours of video being uploaded to their servers every minute. What they don't pay in streaming rights, they pay in storage and bandwidth costs, plus a couple of peanuts for "moderation", which is probably more expensive in the long run

you forgot to add spotify which is about 12$

Depends on how much you use it. I watch Youtube pretty much every day for at least an hour, while using Netflix or other streaming services about once evey few months. I use Spotify every day too, just because I like their app more in some ways.

Well it also includes a streaming music service which are normally $10/m on their own.
