"All of Mastodon" isn't even a coherent concept. Is it everybody using code derived from Mastodon's original 2016 source code release? That code doesn't even support the current protocol, it was written for GNU Social compatibility using a completely different protocol. Everybody who's updated to the most recent version? Plenty haven't. Anybody who can communicate with a Mastodon server? I wrote a 30 line Node script that could do that last month. Etc, etc, etc.
