This right here. He's right you know. Everyone knows that Mastodon can't handle this amount of users and after 6 years, it's enough to see that by itself it has failed, (unless you count Truth Social as a great example of a Mastodon usage that has more users than Mastodon itself in less than a year)

It is not early days anymore and no non-technical user is interested in hosting their own servers for chatting with another person. They don't care about decentralization as even if they tried they will recentralize to the main Mastodon instance.
