Note, though, that it wasn’t the youtuber who submitted it to Hackaday.
I’ve had a couple of my videos show up there and I have no idea who the user was that submitted it, nor what their motivation was.
(Yes, I saw the username, I mean it was a complete stranger who did it)
Maybe not, but it is a default app, and the vast majority of people can’t be bothered to install something better.
