I agree with the overall spirit, but this is a bit shallow, no? Not much of an attempt to argue its points. It makes some claims, refuses to elaborate, then leaves. Feels written for people who already think the same.
Because of this as well as poor financial management, Cohost will pass out of internet culture with little impact
Would decentralization have helped it make a much greater impact? Would it have helped Cohost survive? Seems to me that financial issues would've killed it regardless.
What you're describing sounds closer to how atproto is supposed to work, but it's yet unproven in regards to decentralization.
