It's really not. The most perfidious thing centralized platforms do is promote controversial content to increase engagement. This is a double fail of centralization because, first, that's their business model, and second, everything they screw up happens at scale.
Decentralizing things would create, let's call it, algorithm diversity. Not everybody is finding things the same way as everybody else, so esoteric garbage mistakenly promoted by somebody's bad code doesn't have as much reach.
And the business model could be different. Or at least there could be more than one.
