It seems to me both strategies articulated here reflect three values.
Obviously you were very clear in not explicitly judging the strategies you mentioned, but reading them did make me think about how someone who did find them wise might respond to situations where the net impact of the helpful act decreases between when it could first be implimented and when the receiver would offer explicit consent.
Supposing for whatever reason, the value of the helpful act would cease to be beneficial right shortly before the user would consent, but up until this moment the net impact would be constant. Can I conceive of a sense in which there would be benefit to waiting until the last possible moment, as close as possible in time to when the user would consent? Or is the notion of receiving consent all or nothing in this sense?
