Most businesses are never going to be a Netflix or a TikTok or whatever. Yet their businesspeople are absolutely infected with this mindset. And don't get me wrong, it is a disease and its primary symptoms are exactly what OP is complaining about.
So instead of building practical, easy-to-maintain systems we cater to the dreams of excessively optimistic (can you even be anything else as management?) nontechnicals who think every idea is going to require the kind of scale and tooling that someone like Facebook has at their disposal. And they're backed up magpie engineers more fascinated with interesting than functional infrastructure.
Ironically, that very tooling and scale ends up demanding even more resources which demands even more tooling to manage. What a virtuously (hah!) profitable phenomenon for the vendors of these tools.
Good grief.
