Hi Richard. Posted the link here - Story of @zloirock, core.js author - better read it in full. It is pretty major, because all media platforms are using core-js, but very few can understand and fix the problem.
EDIT: I expected zines like Vice Motherboard to cover it, but they are out of the loop with their editorial - site:vice.com core-js - Google Search But in that respect they are just as good as SustainOSS in covering this story.
