This sucks. Matter is a closed ecosystem, enforced using a public key infrastructure (PKI) and device attestation certificates. Thread seems to require paying royalties if you want to ship devices. It’s disappointing that IKEA claims that this move is towards a more open ecosystem.
On top of that, the switch breaks compatibility with existing hardware (except for the Touchlink functionality). If you have a bunch of Zigbee devices, but at some point want to add some of the new ones, you need to start thinking about replacing all the perfectly working Zigbee devices or have a fragmented network.
