I'm baffled by your contributions to this thread. You've read the thread, you've commented on the thread, if it isn't your thing, just move along. You seem quite confused about what's an extremely basic concept. Youtuber makes a living from filming their family's lives and broadcasting them online. Viewers have opinions yet aren't permitted to express them on the Youtuber's platforms, so they come here to do so.
For what it's worth, I'm a 31-year old, degree-educated professional in quite a senior role, with a husband, gorgeous dog, lovely home, hobbies and active social life. I spend probably 10-30 minutes a day scrolling through online forums while I'm relaxing. It's no drag on my time, but thanks for the (faux) concern!
