The filter policy isn't Conroy's policy, it's Rudd's. Conroy's just the poor whipping boy who has been tasked with the policy because it falls under his portfolio.
As for your question, closest I've seen is a couple of months back when Rudd said on Sunrise he made no apologies for the filter. That's it.
Rudd's not spoken about the filter during QT so far. As I said earlier, the filter is Rudd's policy so he's all for it.I'm a person who, for some reason?, enjoys watching question time and I've not seen/heard of him saying he is for the policy but then I've not seen/heard him say that he is against it either.
