I think these things become kind of inevitable in big companies once job-hopping careerists take over most of the decision making, optimizing for the short-term metrics that make them look better. It doesn't help that big companies tend to encourage their performance review / promotion culture over time to be hinged almost entirely on delivering 'impact' through these metrics. Of course it's done in the name of being fair and data-driven.
