People care what other people think, it's how humans work. If this is missing, it usually shows up in behavior where one routinely hurts themselves or others.

People care what other people think, it's how humans work. If this is missing, it usually shows up in behavior where one routinely hurts themselves or others. Another thing to consider is that when people casually leave someone out. For example, they regularly share their experience on a platform, because most of their friends is on that platform. If someone is not on that platform, they get left out of that experience sharing, if someone doesn't proactively reaching out to them, which I'd say is rare. This leads to the non-majority getting more and more isolated from the rest of the society. Another angle is when people in power, businesses, or other significant figures like teachers exclusively use such platform. If the kindergarten instructions are on Whatsapp, the young parent better install that, fast. This is all related to the network effect, whereby the value of a good or service comes not from the intrinsic value of the thing itself, but rather of its users. https://en.wikipedia.org/wiki/Network_effect https://en.wikipedia.org/wiki/Network_effect
