/Because the vast, vast majority of internet users are uninformed, highly susceptible to peer pressure , and love to build and follow social norms for superficial reasons./
I offer a less patronizing explanation:
Social interaction requires other people to interact with. A platform with more people can provide more social interaction. The average person does not make the choice to use larger platforms because they are uninformed or affected by peer pressure. They make that choice because the thing they value most in social media is a large userbase.
The average person does not claim to want something more out of social media. They don’t care what advantages or disadvantages a platform has.
There are of course people who claim to care about these things and still continue to use more popular and worse platforms, but they are far less common than you seem to think. Also the fact they aren’t changing their behavior doesn’t mean they don’t actually care, it just means they care more about other things.
