I would like to see the Fediverse grow overtime, also we haven't had to deal with a Decentralised network across the internet before, who knows what may happen.
There is a big difference between slow growth over time though (say a few percent of the existing user base every month) and a giant influx of new users (say 10 times the existing user base in a single month). The latter destroys everything the community was about since nobody knows the unwritten rules and new users copy bad behaviour from other new users.

You say that while using the WWW, a decentralized network of Webservers and Webbrowsers all Access the world.
And you say that while using Domain names, which certainly don't come from your /etc/Hosts but from a decentralized DNS Network of servers all around the world.
That's different from a Protocol that anyone can use, boot up a server that has access to the whole Fediverse active posts & user base.
The Fediverse is making it so much easier for people to have users across their own social network platforms, bending the protocols to work with what vision they have, well still allowing others to access it.
