I don’t see the justification for following the leniency. “He is reliable” isn’t enough
If Rav Oelbaum, Rav Steinberg or Rav Nevensaul muttar it, they are reliable (Like I said I dont think Rabbi Mizrachi was endorsing the product)
I was talking about Shabbos Mode in that quote, not this switch.
There’s apparently some controversy about Rav Nebenzahl’s position. I actually found this on their website. Now, maybe they’re correct that some are out to get them (they list a few), but something is absolutely fishy about the endorsements – and this is apparent just from their site, although they, of course, claim that it’s all the others who are wrong.
You should ask the other two what they say. I’m also curious what they’ll say.
