I can’t find it now, I remember the CT announcement posts explicitly calling it out as “not a blockchain”. The CloudFlare announcement also makes fun of it:

> Certificate Transparency brings accountability to the web PKI using a technology called a <del>blockchain an append-only public ledger, </del> an ordered list.

Crypto is really good at co-opting existing terms (crypto, Web3 for eg) and we shouldn’t let it go the other way as well, calling an ordered list a blockchain.
