> They ran the key through some stupid script that zeroed out all the bytes except the last one.

If a script zeroed out the private key, wont the public key not work anymore?

CAB has nothing to do with trust/distrust here. Its the Root CA Store Operators (Mozilla, Google, Apple, Microsoft, Adobe) which have to distrust here.

Google (GTS) has done the same. GTS controls GlobalSign R4. GlobalSign R4 was a root cert which was created by GlobalSign and later sold to Google.

If a bad actor starts buying up CA's, then very quickly that CA would be distrusted by Root Cert Store Operators. No different than what happened with DigiNotr and Entrust.

What you are proposing sounds like DANE with TLSA and DNSSec. Great idea but most CC TLDs are still using 1024 RSA ZSKs. Right now PQ DNSSEC is very uncertain. PQ DNSSEC will likely take about 5 more years or so to standardise. And thats too late for companies like Google and Cloudlfare which want to go PQ Crypto by 2029.

A very welcome move because for years Cloudflare has freeloaded certs from Let's Encrypt without sponsoring Let's Encrypt finacially. Though Cloudflare has contributed in otherwise to the ecosystem like by running CT logs etc.

Now, it looks like WebPKI is going to fracture into two regarding PQ Crypto. With Google (GTS and Chrome), Cloudflare and Let's Encrypt all preferring MTC and legacy CA's like Digicert, Sectigo, Globalsign all heading towards non MTC.

If Cloudflare would not have decied to become a PQ CA for MTC. We would have a duopoly with GTS and Let's Encrypt. This is a worse off situation. Therefore I welcome Cloudflare CA for MTC.

Also, its not like they are going to make any money of the CA business if they are going to issue DV certs for free. It will reduce the pressure on Let's Encrypt from carrying the burden of securing 60% of the world's webistes.

then the agents would request regular html when blocked

I am guessing Cloudflares delivery costs would be much lower than the compute costs to convert on the fly.

So they basically re-invented Gemini (the protocol not the AI model)
