Matt Mullenweg has a great blog post with both positive things to say about Cloudflare and a critique of EmDash. So I was right yesterday that “spiritual successor” was the wrong way for Cloudflare to pitch this. From Matt, about why WordPress can be run anywhere:

It’s all built on open source and web standards. You can run it anywhere; there’s no lock-in.

That’s why we do what we do. It’s really hard. You can come after our users, but please don’t claim to be our spiritual successor without understanding our spirit.
