Both ways are a wheel with a hub in the center and spokes out to the wheel. The users are the spoke/wheel location, the “corporation” is the spoke/hub connection
The Old Way was users connecting to a corporation that provided a service. The corporation controls almost everything.

Lemmy is the hub, instances are the users, and communities are the data shared.
