This is pretty naive though. Everyone so far who's ever sent me, er, "home videos" has later decided to stop sending me such content and would probably revoke my access to it if they could. Maybe I'm just a sneaky jerk, but backing up content that I would like to see again seems like something I'd try regardless of how the relationship was at the time. I don't mean anyone harm and I'd not distribute someone's videos without their consent. I'd just want to keep the ability to look at them.
So let's say you go through the hoops to use this app. Then you'd immediately break that trust, while still in the relationship, by recording the videos?
Yes. For me it would depend on the nature of the relationship (and "maybe I'm a sneaky jerk"). But often people send each other "home videos", or create them together, outside of what I'd consider a Relationship (love & trust & all that jazz).
Isn't that exactly what Rumuki is trying to solve? If there's enough trust in the relationship in question, the people involved should just solve this with the conversation: "hey, did you delete that video after watching it like we agreed?" / "yep, you?" / "yep".
I do, but see my further clarification below. In any case, it doesn't matter whether I personally would do this. It's clear to me that a bunch of people would.
And I KNOW complaining about downvotes is like the HN kiss of death, but whoever hit that down arrow because they disapprove of my (hypothetical) conduct should really rethink their use of HN votes.
