Because adding brains and storage to hardware is expensive. And putting simple things on customer prem means less things can go horribly wrong.
And people actually like controlling their hardware from out-of-the-home, which makes doing everything locally even more complicated.
When you start trying to present end-users with a graph of whatever metric you want, you run into issues with storage, response time, CPU usage, storage, the web front-end, storage, etc. Then you have issues updating all that.
And if you want to do something like, say, comparing and benchmarking against other users you can't.
Really, only technical people care about this kind of stuff, and they can go ahead and write their own or use HA.
> Because adding brains and storage to hardware is expensive.
I disagree with this; it's expensive if you need the device to support Python or C# or similar. A $5 esp32 chip has enough storage and RAM to both act as a controller for hundreds of devices, AND run a minimal webserver to provide an interface for the user to automate those devices.

I second this: people who want home automation also want the ability to control it from their cellphone anywhere in the world. Unless they are technically proficient enough to setup their own public-facing server that is on 24x7, the customer is almost always going to prefer the device that is connected to a proprietary vendor's cloud.
