Lemmy

This keeps on being asserted but it is far from true. If defederation happens or your local goes offline, posts/comment history/profile/votes will remain on other widely used instances and out of your control.

A large instance has already defederated with 2 other larger instances. If you run a personal instance I feel it will be very, very common for you where you will be locked out of managing your data.

You can expect defederation to happen all the time as that is a deliberate part of the open federated model.

And that is to say nothing about federation simply breaking sometimes.

I already have content that exists on other instances that will remain forever and I've only been around a short while. I don't care personally, but people keep asserting this claim that only bad actors or scrapers will dupe your data. Federated data is very different than a non-federated copy for many reasons and that matters to some people. Everyone should understand deleting your account, or modifying your content will often not remove your content outside your instance, and many people engage outside their local. It will likely exist in federated, Lemmy searchable form forever in some capacity (in the current iteration anyway).

Not trying to spread FUD, but if we want to maintain users, they have to be educated as they will find out eventually and not be happy.
