Why are general-purpose OS not good for IoT applications? Is it too complex and not focused enough on the actions?

I mean, your answer is more or less spot on, something like, let’s say Raspbian running on a raspberry pi, while pretty minimal it can still be considered general-purpose, it does a lot of things in the background, it always “ready” to run whatever you the user types or clicks on, and with that all sorts of processes in the background ensuring internet connection, maybe through wi-fi or cable, a video output, usb devices, all sorts of things. And IoT devices will generally have a handful of purposes, and having something programmed to only do one thing is much more efficient and cheap than something that’s always doing a lot of little things.
If you run some sort of system monitor on your os right now you will see a lot of processes running, and not only that, within these processes there can be many more things going on.
Also security… but… hm idk about that one.
