Personally I find this annoying as hell.

I was adding some devices to my 2500 sq foot home, an old farmhouse that is full of little nails in the downstairs that kill radio propagation. I was hoping adding a second SmartThings hub would make devices in a room far from the hub completely reliable.

I found out SmartThings hubs were sold out everywhere and first chalked it up to the supply chain crisis. Then I found out Samsung is licensing the technology to vendors I've never heard of. Not only do I not take it for granted that these third-party products will work with my setup, but they are also sold out everywhere.

I am very happy with the SmartThings experience, particularly with writing applications that use it. This kind of platform abandonment is how a firm goes from #1 to zero in internet time.
