My charitable read on this is that an individual vibe-coded both the post and repository and was able to publish to the Cloudflare blog without it actually being reviewed or vetted. They also are not an engineer and when the agent hallucinated “I have built and tested this and it is production grade,” they took it at face value. You can tell since the code is in a public repository and not Cloudflare’s, which IMO is…

I don't know why it being potentially vibe coded or vibe written exonerates the author. "Your job is to deliver code you have proven to work [1]." It is your duty to ensure your work works, no matter what tools you used. You don't get to pass the blame on an AI agent any more than you get to blame intellij autocomplete for your buggy code.

Furthermore, I don't see why we are extending the principle of charity to cloudflare, a billion dollar enterprise controlling a significant part of internet traffic self identifying as a "utility." If cloudflare deserves more of something from us, it is scrutiny and accountability, not charity and deference.

Let's look back at 2023:

Welcome to Wildebeest: the Fediverse on Cloudflare https://blog.cloudflare.com/welcome-to-wildebeest-the-fedive...

Wildebeest ceased maintenance one month after the article's publication, adding a similar comment several months later[1]:

> :warning: This project has been archived and is no longer actively maintained or supported. Feel free to for this repository, explore the codebase, and adapt it to your needs. Wildebeest was an opportunity to showcase our technology stack's power and versatility and prove how anyone can use Cloudflare to build larger applications that involve multiple systems and complex requirements.

    5 - A production-grade Matrix homeserver [...]
    5 + This is a proof of concept Matrix homeserver [...]
This whole thing in a nutshell. Bold and sad to see this. Cloudflare has/had such outstanding posts that I really like/ed to read.

Hubris?

Unfortunately that one isn’t new

So the original post had this added to the top: > This post was updated at 11:15 a.m. Pacific time to clarify that the use case described here is a proof of concept. Some sections have been updated for clarity. But then the bottom still says: > Our team is using Matrix on Workers, handling real encrypted communications. It is fast, it is cheap, and it is arguably one of the most secure ways to deploy a homeserver tod…

> Our team is using Matrix on Workers, handling real encrypted communications.

... Oh, dear.

what? that's like saying "you should implement TLS instead of HTTP"! They do entirely different things: MLS is a key agreement protocol, equivalent to the Double Ratchet that Matrix uses for E2EE today. Matrix can use both.

Terrible analogy. MLS is an IETF standard. The server is easy to write, and easy to make scalable (no complicated merge algorithm required, unlike Matrix). Finally, individual chatrooms scale to an order of magnitude larger size vs. Matrix. MLS is superior in every way to Matrix as it exists today if you need to implement encrypted chat rooms for your app. Source: Guy who has implemented both, including extending Mat…

What on earth are you talking about? They do entirely different things! MLS is an E2EE protocol, whereas Matrix is effectively a conversation-syncing protocol which supports multiple E2EE mechanisms, including MLS.

Source: Guy who started Matrix, was in the room at IETF 101 when MLS was proposed and ratified it for Matrix, and has been working away on the various approaches to use MLS on Matrix.

Days after the fake story about Cursor building a web browser from scratch with GPT-5.2 was debunked. Disbelief should be the default reaction to stories like this.

It's clear that on Hacker News many people have made absurdly deep investments into this "technology." There's going to be a long period of pearl clutching we have to dig out of until we get back to the standard hacker ethic of not believing anything published by corporations.

In all seriousness Cloudflare was usually pretty good in terms of blog posts.

“This architecture shifts the paradigm for self-hosting. It turns "running a server" from a chore into a utility. You get the sovereignty of owning your data without the burden of owning the infrastructure” Yeah, this is just shameful. Obviously written by an LLM with zero oversight. If this engineer doesn't get fired I'll lose all trust in Cloudflare.

He shouldn't get fired. For all we know he might actually be a decent employee who had a, ekhm, temporary lapse of reason. He didn't destroy anything (except damaging CF brand).

The best CF can do is to post a post-mortem and improve procedures so that can't happen anymore.
