This is some sort of absolute, fundamental difference between the early web and now, at least how I experienced it as a teen in the late 90s in Hungary. Back then I made a site, because you wanted to make something of my own, in my style, as I wanted. There was nobody else online from my friends, and I made new friends online. I actually found my age people on ICQ, within the same subculture.
This "oh my friends are there" approach is what destroys everything. More precisely the people who can't decide for themselves.
The old web was a very different place, it wasn't as centralized and there were significantly fewer people around. There were specific forums that you'd go to for specific topics. Say you were interested in West African dances - there was usually the one forum where all the West African dance nerds hung out. At most a couple of different ones. And they were very small communities. If there were issues with the admins or moderation users could and did do mass walk-outs and create a new place.
Think about why they should care about your answer and if there's any proof that it bothers them to the degree that they may view your alternative platforms as actual solutions.
