I agree with the overall sentiment, but a smart switch would be harder to change than a smart bulb most of the time. Smart switch would require electrical work to replace. A smart bulb can just be swapped. If anything the toilet is a good proxy. A smart flush means it won’t manually flush. If they had done a smart fill you could just manually fill the tank with water.
In this post it seems as though smart is being used to mean completely replacing the thing. I think that having both smart and dumb options is ideal, but in this particular context I think the reference point is that the smart object does not allow a manual override.
