So ... Tumblr...

The narrative people are having is how your centralized webhosting needs to be neutral and not censor content they don't like (nevermind that they too have freedom of association)

The narrative people should be having is how centralized webhosting like Tumblr means that whenever some rich upperclassmen decides they don't like something it is effectively and completely suppressed, and how you should self-host your own blogs or other content to avoid that.

But, the more things change, the more they stay the same.
