I thought about this already for a while and with Lemmy and Mastodon the opensource community has a place to really try itself out and coordinate. Then even things like open-source planning-systems (like at Amazon) and AIs are possible.
At least in Germany there is currently no really political movement that could be described as left-libertarian at least seriously. Maybe the Fediverse could be the root for something like that.
Or will the Fediverse will become more like the new landscape of the internet, which encompasses everything and in which every party will need to move and have a certain stance to somehow?
For me Lemmy, mastodon etc are tools, like email or http. People which use these tools are very different and have very different political views. So, for me the answer to your question is “no”.
On the main fediverse you can really see it – the thing everyone has in common is a back-end protocol. That’s about it. You get trans instances and terf instances and no, they won’t be joining hands to sing kumbaya.
The World Wide Web is another example of this that’s much older. How many people reading this agree with Stormfront? Probably not that many. And yet both you and them are sharing the use of a variety of TCP/IP, HTTP, and HTML protocols and platforms.
