If such people raised concerns and they had been overridden they way you describe they would sadly have left long ago.

It is not that companies become consciously malicious or are incompetent to start with, it becomes a vicious cycle, as more and more poor management and engineering talent join, the good ones leave, and the cycle continues.

Acquisitions and merge stave off the slow slide into irrelevance for a while, till the best of the new guys leave too. Systemic cultural changes is very very hard to achieve in large organizations.
