That's a false, uh, decachotomy (?), it doesn't have to be a centralized organization of any kind at all

It doesn't have to be, but things seem to be inevitably gravitating towards a centralized model because it seems people care the most about their User Experience and everything else is secondary (privacy, monopoly, monoculture, worker abuse, etc).

The word you are looking for is dichotomy.

I think the parent commenter wanted to emphasize that there are more than 2 options (di- = 2, deca- = 10) to choose from...

But false decachotomy would imply there are more than 10 options. Seems weirdly specific.

Such an organization, designed to respect input from consumers, workers, and global community members affected by negative externalities might be called a "co-op."

It's a matter of oversight, transparency, accountability and motivation. In the case of Google, they have very little oversight, nearly zero transparency, they are accountable to only their shareholders, and their motives are exclusively profit.

They have no interest, or even means of producing, a publically good internet. They can and will only produce an internet that is best suited to make them money. And with that there will be inherent conflicts with what is best for the users.

At least with a government you get some of the transparency and oversight, public control and no profit motive (if you cap campaign financing that is)

Some organization structures are better suited to do different things.
