Why should I care?
Rav Elyashiv, as Chashuv as he may be, is not my Rov, neither is he my Rov’s Rov, or my Rebbe, or my Rebbe’s Rov or Rebbe.
His statements, even if they are truly said by him (which is highly questionable), do not affect me one iota. There is no reason why I should follow what he says, any more than listening to the Gerrer Rebbe (whom I assume is also a big Tzaddik).
They may make others think I am less frum for not caring, but I don’t really mind what others may think.
