dentangle, Multicast is, essentially, networking with consent.
Only traffic that we consent to receive will be sent to us, and we can revoke that consent at any time. Multicast is opt-in.
Conversely, unicast traffic is opt-out. We can only block unicast traffic with something like a packet filtering firewall.
I'm trying to explain what we mean by #multicast in the @librecast project in plain language. 🤔
