To attempt to reach synthesis, I would say it could be valuable as a therapeutic exercise for yourself. However, my own experience is that choosing to vote with your feet doesn't really effect change that often. I've done it twice and while it felt good, life just kind of went on at the places I left behind.
The remaining people/mgmt will either do nothing, see it as a squeaky wheel thankfully now being gone, or maybe even add "we need to do something about attrition" to quarterly goals but not actually change anything meaningful.
So even if you get past the "oh they were just disgruntled" justifications, I find that companies are more likely to add ping pong, beer fridays, or even bump compensation before significantly trying to change the culture.
