So out of the one sentence that I wrote you decided to ignore the part where I wrote that decentralization was referring to centralization of content? Another word for centralization is consolidation.
You might want to look up the term "walled garden":
I didn’t see the word “content” on first reading. I never have encountered Google or FB created content (other than open source code), and I also don’t use their news aggregators (or other services), so (with the exception of YouTube), I don’t think of them as being in the content game at all. Anyway, I’ve been happily ignoring their walled gardens for decades, and using the decentralized web for news, etc.
Certainly, they’re in the infrastructure + surveillance business, and (especially for Google) that’s concerning.
Also, “Decentralized” is a technical term. Google runs a large, decentralized infrastructure, based on web technologies.
“Consolidation” is usually used as a business term, and is orthogonal to centralizing operations. For instance, many companies have outsourced payroll to one centralized company. That does not mean their industries are consolidating.
When people intentionally use words wrong, it is bound to lead to confusion.
