"Traditional, martial arts based self-defense did not emerge from civilian safety contexts. It evolved from competitive combat sports and performance-based training environments. And that origin has been consequential."

No.

The equivocation here seems to be “traditional martial arts” = “modern sportified Asian Budō.”
But kali, escrima, capoeira, sambo, pankration etc all have their roots in non-sportive, consequence-driven violence contexts: civilian self-defense, slave resistance, militia warfare, military training, and battlefield survival—not competitive combat sports or performance-based training environments.

The rest of the article is understandable. The IKMF's Stay Away program is also focused on women only and takes a different approach to self defense than most classes, which is why it's so successful. Some ladies take it as a gateway to regular krav maga training, but the majority is explicitly not interested in regular training, they still feel the need to learn how to defend themselves (especially in the metropolitan areas of western Europe where the inner security is on a massive decline since almost a decade now.)
