For two, your specific claims about the likely confusion that Eliezer’s presentation could induce in “laymen” is empirically falsified to some degree by the comments on the original post: in at least one case, a reader noticed the issue and managed to correct for it when they made up their own toy example, and the first comment to explicitly mention the missing unitarity constraint was left over 10 years ago.
Some readers figuring out what’s going on is consistent with many of them being unnecessarily confused.
