It’s all fun and games until venture capital kicks in, and exploits that central user data store to further centralise the rest of the network. Even then yes, I think that Mastodon has a lot to learn with Bluesky, on how to make user experience smoother.
I get what you say, and I agree; but when it comes to the average user I wonder if they’ll even get it. They don’t think on the grounds of a “protocol” or a “platform”, it used to be “site” and now “app”. They do it even with email, of all things, even if it’s one of the oldest cross-platform protocols out there!
