Not a great analogy, any network manager worth his job is not going to want to support xp machines on the same network as W10. It’s an obvious security risk and I’d expect them to do similar to what Sonos have suggested and isolate them from the other devices.
Sonos have (now) said that legacy systems can be segregated from current devices, allowing current devices to maintain updates.
I think that I’ve already said Sonos comms have been poor on this, certainly its impacted their reputation.
That said it’s still unusual for a tech company to support hardware platforms for this length of time imho.
