You are assuming that in these companies the managers are a completely separate class, but the truth is in most of big tech most senior developers / architects feed directly into product roadmap and management. In fact most of big tech make a point of trying not to hire pure managerial folks. In other words it is not purely management who are responsible for most user-hostile interfaces, ethically dubious business models (how to optimise gaming addiction) or bloated infrastructure (kubernetes when it is not needed,...), highly-skilled tech folks need to own up for these low-interest rate phenomena as well.
