Eh. “The Internet is getting worse!” sounds alot like “New cars suck!”, “Politicans keep lying!” and “Everything was better back then!” - some sayings like “The young behave awful!” go back to long before the beginnings of civilisation (probably).
So I wouldn’t worry much. Once humans lose interest in something, they move on and the old huts, devices and whatnot slowly erode away. Guess why we are now talking on a federated network - because those big companies started rotting away and the smell slowly starts driving people away.
Just my opinion though. It’s still fun to see things crumble.
