Can someone explain the economics of this?

So, there are a bunch of open http endpoints serving free video feeds and they don't care about bandwidth?

It's not like radio where you broadcast it and people passively receive the signal.

This is a great service for language practice, though. Wish it had a login + favorites system.

I never got into this aspect of networking, so I truly don't know what I'm talking about and wish someone will correct me, but on some level, IP does indeed have broadcast/multicast capabilities that cause the sender's egress traffic to remain independent of the number of recipients rather than being equal to the sum of recipients' ingress traffic, right? Does this only work downstream of the last router, and therefore has limited usefulness on the internet?

I think you are right. Multicast is typically udp and only available on your local net if the router is configured for it. I haven't used multicast in along so I might be wrong. I remember network updates breaking it.
