>The Great Internet Purge
What has to be understood about the social media biz is that the product is the users.
What they doing is actually more like a closing shop sale.
Neo-liberalism is killing the purchasing power of people, and with that the advertisement biz will dry up, since there's little purpose in advertising to broke people.
With ever more aggressive catering to insufferable corporate world views, it will drive off users, and they will be able to fake mass appeal with bots for a while, and then like everything neo-liberalism has produced, disappear. Marx would see this as "the old that is dying" and would urge you to look towards the new that is struggling to being born.
We have to take into account the material reality, why did the capitalists manage to capture communication between people. And here we have to say that it's the servers they could treat as capital which they could accumulate. There are other die-off scenarios, all there servers for the capitalist social media are bunched together in extremely densely and relatively few locations, which means they have become high value military targets, that are very hard to defend and easy to attack, this is to some extend replicating a similar scenario which ended fortresses in the middle ages.
Capitalist crisis is increasing the tensions between rival powers as well as create new factions. Eventually the cost benefit analysis will tild towards attacks against these data centres, this will of course produce a counter tendency where the bunched up data centres produce external costs in terms of military defence spending to deter such attacks. And here we see where the avenue for the new systems to arise is situated, anybody who can deploy a different type of information architecture that does not have this downside will gain a civilisation advantage.
This is what you have to look for.
