That's a bad comparison, since they're fundamentally different applications.

Video conferencing is multicast, video streaming is broadcast. I can essentially opt in to opening a data channel to a peer because its core to the technology and feature set. I don't expect opening a link to a video exposes me to another random person or computer watching the same video.

Another fundamental difference is that video conferences are temporary. Hosted videos are persistent. I can just have a machine hang out watching a video on loop and sniff peers coming in, quite reliably if the video is popular.

Another point I'd bring up is that video conferencing apps' threat model is essentially around unauthorized access. It's dealt with by obscuring the video stream's link, making it temporary, and securing it behind an authorization protocol (on Zoom you have login, password, and manual admitting by the host, for example). That doesn't really fit if you're hosting videos to be persistent.

Huh? All WebRTC is unicast.

Well first thing even in the case of video streaming the url changes with time with the current security measures and hence valid only for certain time

My second point w.r.t comparison is regarding the security of data channels of webrtc which is a pretty secure channel which is used in video conferencing as well but there is no known security loopholes in that and thus no concern
