I saw another interview about the KosherSwitch the other day. Some woman who is using it just speaks about how much easier it makes things. How she once had a guest at her house who drank too much, and needed to stay over at their house. The basement was pitch black so she couldn’t prepare a bed, but thanks to the KosherSwitch, she was able to! Her kids turned off the bathroom light, but luckily, they had KosherSwitch! Then she makes a small comment about how her Rav says it’s ok to use.
I think they minimized the most important aspect of it: her Rav said it’s ok! I don’t look down on this woman at all. She is following a psak from her Rav, which is what she should be doing! But they put this out there to tell us, “Look, KosherSwitch will enhance your Shabbos!” But what about most of us, whose Rabbonim forbid using it? It doesn’t matter how much easier it makes things if we’re not allowed to use it!
The Rav the woman uses may or may not be knowledgeable. I have no clue who he is. But if he did make a mistake, and his congregants are using the switch because of it, he will be held responsible.
