In their excellent article on NAT traversal[0], Tailscale mentions that the UC Berkeley guest wifi blocks all outbound UDP except DNS.

EDIT: According to this[1] issue, Berkeley guest wifi allows port 443, which would solve HTTP3/WebTransport. That's certainly hopeful, and I hope all networks are like this in the future. It's just not a forgone conclusion yet.

That's a case of shipping it 'broken' for those people.

If it works literally everywhere else, and the product is valuable, they'll change.
