Schools only started teaching that rule relatively recently

Recently? The order of operations rules have been taught for more than a century (we can see them in Lennes' letter).

Order of operations in general, yes. Implied multiplication coming before explicit multiplication/division is what's recent.

Implied multiplication coming before explicit multiplication/division is what’s recent.

"implicit multiplication" is not taught, because there's no such thing as implicit multiplication
the "controversy" over it isn't recent either - we can see Lennes complaining about it more than 100 years ago! The more things change the more they stay the same (sigh).
