They are also the main developers of the Mastodon software. It is not just hosting the service. The software needs to be able to compete with Bluesky and right now it quite simply does not. The only way to get the quality needed is to have some full time lead developers. Also they need some proper admins to run the websites. Mastodon social is at 250,000 active users right now, but it is also fairly likely to grow fast with what Elon is up to with Twitter. Just to compare Twitter used to have 7500 employees, with a 1000 today.

There are ways around it, like link shorteners and so forth, but the main point is that Meta is afraid.

Voyager is already cross platform for iOS, Android and web. It is also open source: https://github.com/aeharding/voyager

Usually those artist did get some recognition during their life, but never got into the main stream. That changed due to the main stream changing and the people who did like the art showing it again. That is actually rather easy to do with something like the Fediverse. It just requires a download option. Especially when everybody is aware, that the content will be deleted, that would be a decent option.

Also a lot of content on social media in general is very short term. Stuff like politcal discussions are fairly useless after a few months in most cases. So that can be deleted without much care and again, if somebody wants to preserve it, they easily can just download it.

The thing is that the value is in the communities and not in the old content. So most likely the mods would just post we move to a new instance and a lot of users would follow. We just saw that on the German speakin lemmy instance feddit.de, which was abandoned and now most of the users and communities moved to feddit.org, which is already one of the larger ones.

What lemmy really needs is the ability to easily move accounts and communities. Mastodon has that for users already.

!europe!europe@feddit.org comes to mind as a somewhat political community, with a non US focus. It however has a lot of Germans in it.
