@atomicpoet If they could buy those instances, that's also because they were for sale.
Migration is gonna be difficult for Japanese users. Who's going to run a new Japanese instance that could welcome ~1.2 million users? (if there's really 1.2m active users, Pawoo kind of cheated on this)
Also they all run on an obsolete version of Mastodon (namely 3.3 or 3.4) so no automatic migration.
Pawoo is even a fork that was heavily patched at a time were a lot of features weren't available. They were #1 in creating new features when they were owned by Pixiv.
@atomicpoet And btw, a lot of Japanese people that are aware of Pawoo or even use it don't even know it's a Mastodon server.
