While preferring decentralization is relatively uncontroversial, the simple problem is the economic incentives to do it do not exist, and run very far in the opposite direction.

This isn't as simple as saying Google, Facebook etc. have a vested interest in promoting a centralized view, but that it's basically impossible to make money competing against them with a decentralized system.

There's a definite trend towards late 90s techno-utopianism appearing again.
