This is because the toolchains and architectural assumptions of NPM-based frontend culture are *fucked*. Totally and utterly divorced from what delivers acceptable results for most people, most of the time -- both as users, and as businesses.
This deep truth sits underneath everything else: *the way* these frameworks and ecosystems present to the developer assumes they have no self-control and do not know better. All while justifying their wares on the basis that everyone, instead, has mastery.
