I don't think Dan Luu has some sort of eminent domain over this topic -- I've seen literally hundreds of similar posts, most long preceding and covering the same topic. It's a pretty common decision for people in this field to face, and lots of people have lots of takes.

Not to mention that his post format isn't remotely like DanLuu's. It reminds me more of old Philip Greenspun.

Not that "basic text" is some sort of copyright or something.
