Certainly your prerogative. I get a lot of value out of running Home Assistant (open source) + Zwave lights (local only + industry standard + physical switches for everything) + things like a Bluetooth controlled valve on my hose spigot that's underneath the deck. The only real failure mode is that my server goes down and I have to control the lights with the switches on the wall like a normal person. But I can certainly understand why someone wouldn't want to maintain the infrastructure.
