I don't think that's at odds with what I said. If there's a good decentralized protocol that gets momentum, good for it. But, the interests that build social media apps well in terms of what is successful in the marketplace, usually chose not to do that because it isn't in their interest to do so. They spend a lot of money on marketing, driving engagement, etc, and most don't want to share it.

Email is a bit of an outlier because it gained critical mass before the web was predominantly commercialized.
