The problem here is that you're looking at it from an entrepreneur perspective, while the people building it are looking at it from a privacy perspective. I don't use Facebook because of the reasons it's popular. I don't want my information easily accessible online, and I do want as much control as possible over who sees my information. I believe it should be easy to give and revoke access to my information and content. The European solution here is to legislate our way to that end goal, whereas the "market" way is to make something that's appealing that gets you most of what you liked about the centralized service, but with more control over your data. And that's why I'm so interested in projects like ActivityPub and Matrix: it's not because I think they'll become popular, but because of what will happen if they become popular. If I was to invest money, I'd go with Facebook's business model every time, but if I'm going to evangelise something, it'll be something like Mastodon or Riot.im.
