Then you can just install something else on it?
I get that it sucks when a device is locked, because you might need to install a different OS for a multitude of reasons, but as long as you are able to install whatever you want I dont blame the manufacturer.
Edge has started doing that too, whenever I download something from my Home Assistant instance while at home I have to rightclick and say that I really want to download it.
As long as such an option is available its not too bad.
