Your argument does not gain validity by adding irrelevant verbosity:

Federation ain’t doing great.

The linked issue has nothing to do with this script or lemmony.

Federated replication load scales with the number of instances multiplied by the number of communities they subscribe to.

That's a hasty generalization that you just made up.

Server counts are growing at ~10x per month.

That's great! I hope they keep growing!

The defaults of this script encourage single-user instances admins to bump their sub count ~70x from something like 100 communities to something more like 7000 communities.

Nobody is encouraging anyone to do anything.

Users of this script actually literally don’t understand how federation works. They think they’re proxying through to the upstream instance while they browse rather than getting firehosed with the entire lemmyverse by they’re asleep.

That single user asked a question and got berated by a jerk.

It doesn’t take a rocket surgeon to figure out that global federation worker queues are not in great shape, or that a default that encourages single-user instance owners who have no idea what they’re doing to bump their sub count 70x isn’t helping the situation. If you think this is in my head I can’t help you. But I can help others understand that running this script with default settings is an awful and unnecessary idea.

You can help others understand what it is. That's a great thing to do. It would be nice if you could do that without being a dick.
