Teenagers right now have a different attitude about how their camera interacts with the world, by virtue of having been raised in a perpetually-filmable world. For a teenager, everyone they know has had a camera with them pretty much as long as they can remember. They've already got a camera pointed at them all the time. It only takes a few seconds to start filming something with your phone.

People who are 30 are going to be weirded out by this. People who are 18 are not. They already have the assumption that anything they do in public might be filmed and shared on social media. And they want to be able to quickly film anything they're doing in public and put it on social media.
