If I may suggest, I recommend reading up on the concept of comparative advantage. Economics suggests that an org that spends more on self serving Mastodon or any service outside their core offering costs should be willing to offload that to a specialized service if the service offering is lower.
I know no commercial organization running their own Mastodon - all instances I know are some non-commercial communities who are just too attached to their favorite domain. As communities run by volunteers, the cost is more important than the volunteer effort.
Are we now giving bureaucrats as a positive example? I see so many people running closed servers with just a couple of accounts of it, which is another failure of Mastodon - not easily allowing people to use their own domains as identities instead of having to run a whole new server, which is a total waste, and not helping the ecosystem!
