Something is re-broadcasting the announcements back onto a network.

I wasn't involved in diagnosis, so going from what I was told: At work,
they had this exact same problem in the SF office and they discovered
that Sonos music players automatically bridge together any networks they
find and join, so there's a bridge built into a player device, which
caused packets from MacOS on wifi to go out on wifi, be bridged onto the
wired VLAN on the Sonos, then come back into the laptops; from this, it
seems it would only affect machines plugged into a wired network.

(At which point, one of them suddenly remembered that $previous_employer
had banned these devices and now knew why).

Something similar may be happening?
