Well... probably because carriers were trying to charge by the
bit/packet, and vendors were trying to sell centralized, proprietary
videoconferencing services. Interoperable multicast makes it all too
easy to distribute such things. (Consider the demise of CuSeeMe and IRC
- can't see that Zoom or the myriad of chat services improve on the
originals.) Sigh...
