I think at least right now this is reasonable: It's off by default, and if you choose to turn it on, they don't use it for anything themselves, but Comcast is disclosing that it may be forced to give the data over with a legal request.
If I was advising Comcast, I'd tell them this is a dumb thing to introduce because just the perception of bad behavior is not worth any particular benefit, but whatever. I can't imagine someone deciding they want a Comcast plan because it offers this, and there's no way for them to monetize it without almost assured legal backlash.

These days it is never safe to assume that opting-in does anything more than making some of the information that's being collected regardless available.
Although I actually agree with you that it probably isn't doing anything by default to the extent that it isn't doing anything yet because it's new they haven't worked out how to monetize it.
