On the one hand, it seems slightly less ideal to have the same organization that develops mastodon also providing hosting for it. On the other hand, they probably have a better chance of doing it well.

Yeah, I could see it going two ways. On one hand, they could devote too much time to their for-profit arm and neglect the FOSS branch, or worse, make the .com a favored child over the .org, like WordPress does. But on the other hand, they could be like Canonical which, while they’ve made some questionable decisions with Ubuntu over the years, has pretty staunchly put open-sourced all of their improvements and opened up their improvements to everyone downstream.

And I too miss moz.soc.
