It’s pretty clear that you didn’t actually watch the video… The video has nothing against TADC…

Even if all support is dropped, everything is running on open source software, so nothing is going to stop working as a result of dropped support.

Finding replacements might become tricky at some point though.

It doesn’t really matter whether Zigbee was merged into something else, because it simply doesn’t have any technical means of phoning home. It simply can’t access the Internet.

There’s no intermediate corporate owned servers, there’s no proprietary software.

So it doesn’t really matter what the corporation does because it can’t affect my “smart” devices.

That depends on the kind of “smart”.

I have a bunch of IKEA “smart” light bulbs, but they are connected through a Sonoff USB Zigbee dongle. And all of it is controlled through the open-source zigbee2mqtt and home-assistant.

No one, but myself and my family, have any control or ownership of any of those devices.

That’s definitely not what I’ve heard, please elaborate.
