Popa,
Yes. But it is too soon to infer from Rav Feldman’s silence that he hasn’t. I don’t know the context under which Rav Feldman was speaking (I think it was a shiur), but he might wait until the next such context (i.e. the next such shiur) to clarify.
I don’t expect Rav Feldman to retract from his general statements, only from the statement calling Lipman a rasha.
