It's a better marketing indeed, but that doesn't answers the op's question.
Between something opensource and trusted, and a proprietary potential backdoor that can send the data back to the Zuck himself you'd probably want to choose the former (cause you never know with closed sources).
I'm glad that he has shared the link as for me it's definitely useful. It's not a competition and I don't care what media talk, that's not about money.
There isn't any hope for something called "yj_nearbyglasses" if nobody outside of technical people know about it so OSS is kind of a moot point here.
Outside of that, this project giving scary warnings is something I cannot recommend to others.
