Well, in your bubble maybe. I can assure you the majority of people your age barely grasp the concept of the internet, let alone online gaming. Same goes for people in their 20s. It's like cars for many people. Sure, they know very well how to use them, but have no idea about what other people do with their cars, like racing or off-roading. They might have some rough idea of what it probably is, but no clue about all the intricacies.

Nowadays most people use the internet, but that doesn't mean they understand the pain when someone leaves your online match. Not everybody is playing online games, let alone online games where a leaving teammate actually matters.
