I read it as though he was trying to say '[you are] opt[ed] in by default'.

Now granted, he did not say that, and I only reached that conclusion by the rest of this conversation, but I think to have meant that and said '... was now also opt-in by default...' isn't unreasonable.

Just sharing since you mentioned you couldn't see how using that term for the opposite would make sense.
