I wouldn't be so quick to judge. Big companies are actually like a conglomeration of small companies under an umbrella company. The culture is 20% upper management, 80% local management, and so your experience will differ greatly from department to department. Bad managers exist in most companies. They can and do target people for personal reasons, and usually the targeted person doesn't have the protection or political clout to defend themselves, so they're killed off and life goes on. I had a similar experience at Canonical of all places, which was a real drag because they were one of the few fully remote companies at the time, and I like the company.
