I think you're conflating two things. Collectively owned, as in how large companies are owned by their shareholders. Decentralized, as in instead of a company, its a piece of software, that we are collectively funding the development of and profiting from. As more business can be done with software, with less people, I see this as a way for us to own that software, and contribute to it. If some group of owners charge too much, it can be forked, similar to how a business can be undercut by a competitor if they charge too much.
