Your order is already "algorithm based" and has been for like a decade, companies routinely adjust pricing and even selection based on your ad/surveillance footprint, say hiking the price of it think you got a payday recently (based on spending patterns etc). Idk about McDonald's (though I wouldn't be surprised) but the fact that Amazon does this is very well documented
The data is all public and it's aggregated by a few websites that provide apis. You'd need some kind of tool for analyzing densely connected graphs, maybe load it all into a db and write queries for a start? Or some kind of visualization software
That's just life on the Internet/fediverse in general, there's a constant churn of the small websites/instances as people inevitably burn out. You gotta be mentally prepared for it. I'm really sad since .ee was one of the few good instances that federated with the unpopular ones too
The only solution is improvements to the protocol so migrating instances is less painful. A different form of identity (key-based rather than domain based) would be cool to let us keep handles across instances
