Ouch, that's nasty. It also has security implications. For example, suppose you 
have a multi-user computer, where one user is has a video call going, which 
transfers packets over UDP. Another user could check what port they're using, 
bind to the same port, and steal half the packets, letting them effectively 
listen in on the first user's phone call.

Well, hopefully most conferencing tools use end-to-end encryption. But the 
point is that we don't normally let unprivileged users steal network traffic 
intended for other users.
