They just announced the Matter range, it isn't even in stores yet. I was at the Ikea store yesterday and they still had a good stock of Inspelning and most likely they will still have for a while (they only introduced it a year ago and it seems quite popular).
At any rate, Matter over Thread is still much better than WiFi security-wise (even though it's IPv6 routable) and Ikea's Matter over Thread plug will probably be similar price-wise. And the good thing is that probably even more people have a thread border router (Apple TV, HomePods, some Amazon Echo, Google TV Streamer 4k, etc.).
Still, these Ikea plugs are so cheap and Zigbee is extremely nice, so it doesn't hurt to buy and stock ten now for the future :).
