Firewall blocking is not the point. The point is, that over time through enshitiffication the new device will require call home to unlock. Even when it does not need internet to work at all. But through this the vendor will get a foothold.

Sure you can block it, but then you have a pricey paperweight.

This is not unique to Thread/Matter, they can pull the rug on ZigBee as well, ofc.
