People always have made bad assumptions or had misunderstandings. Maybe the author just doesn't understand ECC and always assumed it was consensus-based. I do things like that (I try not to write about them without verifying); I'm confident that so do you and everyone reading this.

That's likely, or it was LLM output and the author didn't know enough to know it was wrong. We've seen that in a lot of tech articles lately where authors assume that something that is true-ish in one area is also true in another, and it's obvious they just don't understand other area they are writing about.
