Azer Koçulu published a string-padding function called left-pad. It was downloaded 2.5 million times a month. When npm gave away his other package name to a corporation, he deleted everything — all 273 packages. The internet broke in minutes. React, Babel, Webpack — all down. And npm's fix? They restored his code without permission, proving exactly the point he was protesting.
This story isn't about 11 lines of code. It's about who owns open source, who controls the supply chain, and why every npm install is an act of blind faith.
