FYI if you want smart things that are not yet limited by this bs decisions, afaik IKEA products are pretty neat
For the Germans (maybe other countries as well): The Lidl smart home things are nearly all Zigbee based. So far no problems with them and they are, IMO, reasonably priced. I somehow trust Lidl more to not burn my house down than random Amazon sellers. They also sell a Zigbee gateway that phones home by default, but can be converted to local only, dumb mode that works fine with Home Assistant [1] with a tiny bit of soldering. I use these exclusively without problems, even the one I rooted for my parents works without any maintenance.
And now that Matter support is slowly trickling in, they should all be fully interoperable. Currently it's touch and go if a Ikea bulb works well with the Hue hub for example.

It was just too low quality. Motion sensors would activate later and/or less than other vendors etc. Stuff like that.
Ikea is great, Aqara and Sonoff works well as well. They arent much more expensive (if at all) than the Lidl stuff either.
