The one upside of saying "well just quit" is that it creates a community norm of leaving abusive situations while you still can. The objective reality is that these men would have had better lives if they'd quit. It's unfortunate and sad that they suffered, and if the allegations are correct it's awful that Microsoft created an environment where they'd suffer, but the rest of us can learn from this: leave bad jobs early, have a backup plan, keep an eye on your mental health, don't always assume the company will look after you, have enough cash on hand to cover months of living expenses, etc.

Maybe greater attrition rates could have forced MS to improve working conditions, or at least led to higher pay and shorter stints.
