I’m fairly new and don’t 100% understand it yet, but instances are run on servers that require money. Are we heading towards seeing ads or subscriptions to raise funds instead of relying on donations to cover overhead?
Especially with the influx of new users. Hardware upgrades are needed.
Mastodon does this (you can download a full backup of your entire account - although not sure about media) every 7 days, which can be imported into various other Fediverse platform accounts, depending on what they allow.
I suspect that all Fediverse platforms worth their salt will make this a core feature.
