I also don’t like Matter because it removes a barrier that provides security benefits. As things stand currently if you’re using Zigbee or Zwave for smart device connectivity then your hub acts like a firewall and segregates IP traffic from IoT traffic. One of the major features, arguably the feature of Matter is that it acts as a transparent bridge between IoT devices and traditional IP networks like Ethernet and Wifi. Right now the attack surface of my IoT devices is limited to the attack surface of Home Assistant. With Matter every single IoT device is now exposed on the LAN massively increasing the possible attack surface.
