I just read this point in a comment and wanted to bring it to the spotlight.
Meta has practically unlimited resources. They will make access to the fediverse fast with their top tier servers.
As per my understanding this will make small instances less desirable to the common user. And the effects will be:
Meta can and will unethically defedrate from instances which are a theat to them. Which the majority of the population won't care about, again making the small instances obsolete.
When majority of the content is on the Meta servers they can and will provide fast access to it and unethically slow down access to the content from outside instances. This will be noticeable but cannot be proved, and in the end the common users just won't care. They will use Threads because its faster.
This is just what i could think of, there are many more ways to be evil. Meta has the best engineers in the world who will figure out more discrete and impactful ways to harm the small instances.
Privacy:
I know they can scrape data from the fediverse right now. That's not a problem. The problem comes when they launch their own Android / iOS app and collect data about my search and what kind of Camel milk I like.
My thoughts:
I think building our own userbase is better than federating with an evil corp. with unlimited resources and talent which they will use to destroy the federation just to get a few users.
I hope this post reaches the instance admins. The Cons outweigh the Pros in this case.
We couldn't get the people to use Signal. This is our chance to make a change.
One of the things that I feel isn't being thought about much, is that it isn't just Meta's ideology and policies that will harm smaller instances and the fediverse itself; but the volume of data that their userbase will generate.
For smaller instances like mine running on six vcores, 4GB of memory, 512GB storage and a 120Mbps network...I feel like all it would take is a handful of users federating with them and the data flow alone would destroy our resources at the network if not disk level.
No, I don't plan on allowing my instance to see or interact with theirs; but the point applies to all small instances and part time hobby servers. We don't have the means to take on the data they could throw out into the federated network.
If that’s the case, then how will it be possible for the fediverse to scale up at all? If the goal is to replace Reddit and the like, then the goal is having millions of users regardless of if they are all coming from meta or from a whole ton of small instances.
I have some headroom for growth set aside. Since my instance is virtualized, its not too hard to scale it a bit. But there are hard limits due to other projects on the host.
For a lot of smaller instances that are currently running on cheaper VPS instances, they most likely have an upper limit to what their willing to pay for scaling up as growth happens. The only way to balance that is getting tooling in place to purge older data, but that isn't really a good idea either.
Really though, any web platform that hits the public eye is going to face these issues over time. But allowing a large company to federate with a smaller instance will accelerate the issues. You also need to keep in mind that you don't have all the control of these instances, as your users will cause you to federate with more and more content. Sure, you can purge and defederate, but that is a cat and mouse game.
Also, I cannot speak for the goals of others; but lemmon bar isn't run with the goal of replacing reddit. It is meant to be a point of access to the fediverse. No more, no less.
