If the article was intended to be an intro to "Raft" algorithm I would've agreed with your sentiment. But this is what the article starts with:

  Understanding Raft can be tough. In fact, I’ve seen   conversations recently on social media in which actual technical leaders of infrastructure companies demonstrate a lack of understanding (!). Point being, you’re not alone.

Anyway I now notice that the article was written in 2023, probably I'm being too pedantic.
