>>28001>They aren't running buisnessesnor a political party or a union. they are giving out a product for free, which is unsustainable and will eventually lose to actual businesses - they have no economic incentive to grow beyond a hobbyist project
>The federation is the scalability model.it doesn't matter, or rather, this makes things worse. how much would it cost to run twitter? lets assume it is an X amount. now, obviously, like all big social media twitter is a distributed system, so lets assume that there are 100 instances working with each other. the cost of each instance will be, on average, X/100. the cost is divided by instances, but the sum is still the same. now imagine that the instances weren't the property of twitter but of different entities: this doesn't change the overall costs (federation carries a technical overhead so the total cost would be higher, actually)
not to mention that computer stuff is an economy of scale, even if federation worked because of state sponsoring, it would be a necessary tragedy at most. the overhead of federation would be in that case a direct consequence of capitalism hindering progress (centralized and thus efficient and cheap social media)
>freeloaders become enthusiastsno, most people don't care, and there is a limit on how many things you can keep in your head. this is like the libertarian thing when they tell you that you don't need FDA -type agencies because consumers will learn to avoid the food and drugs that sometimes kill people - and then do the same with every other consumer market sector, and keep tabs on the reputation of every single brand on the market. the consumer simply can't keep up with the organized effort of companies
the number of people interested and willing to host instances with no economic incentives has practically peaked, maybe an influx of users would bring a few more, but the ratio would shrink. the entry barrier is the proof that those tech enthusiast share this observation
on a technical side, I have developed stuff that uses as2 and activitypub, and federation, at least as implemented by those, is completely broken. there are no plans for cheap discoverability between instances, you can subscribe to accounts on other instances, but any algorithm capable of traversing the entire network to recommend you content like modern social media does would essentially DoS all the smaller instances. bluesky for example uses a different protocol that supports this feature, and because of that the minimum cost for hosting an entire instance is in the order of millions
