Reputational decline at FAANGs often has little to do with the actual engineers. There are separate product managers / program managrs setting direction and separate UI / UX designers defining how products will look. Feedback from engineers is sometimes taken into account but, more often, will be met with "You don't get the vision" or "You're not the customer." expressed with varying degrees of politeness. The sensible response by engineers is to shrug, do what they're told, and start looking for an internal transfer before the SHTF.
